However, similarities also exist among the feet of many different terrestrial vertebrates. [1], This article is about the anatomical structure. The structures of the hindfoot are usually adapted for transmitting large loads between the proximal and distal aspects of the limb when the foot contacts the ground. (2015) and Zelik and Adamczyk (2016) for overviews of comparative ankle biomechanics in humans and great apes. The results revealed that humans evolved from an ancestor that had a foot similar to living chimpanzees and gorillas. For younger Croatian population the scatter data of the individual foot variables were interpolated by multivariate statistics. [23][24], With a running gait, the foot-loading order is usually the reverse of walking. [25] In addition, the pads of the distal paw appear to allow load attenuation, by enhancing shock absorption during the paw's contact with the ground. The adductor hallucis acts as a tensor of the plantar arches and also adducts the big toe and might plantar flex the proximal phalanx. In this stage of the gait, the knee will generally, but not always, track laterally of the hallux. With the cuboid serving as its keystone, it redistributes part of the weight to the calcaneus and the distal end of the fifth metatarsal. The "plural form feet is an instance of i-mutation." The vertical columnar orientation of the proximal bones of the limbs, which articulate with distal foot structures that are arranged in quasi-vertical columnar orientation, is well-aligned to transmit loadings during weight-bearing contact of the skeleton with the ground. A comprehensive series of variables that describe the essential three dimensional characteristics of the human foot is presented together with descriptive statistics derived from a diverse civilian population (n = 1197), representing a wide age range (18-85 years) and randomly selected in terms of physical demands placed upon the foot in the course of a normal working day. The structures of the forefoot play a role in providing leverage for terminal stance propulsion and load transfer.[6][23]. In the weight-bearing leg, it brings the leg towards the back of the foot, like in rapid walking. Virtual Project Library, Center for Biologically Inspired Design at Georgia Tech, Master of Science in Prosthetics and Orthotics Program at Georgia Tech, Research for this Wikipedia entry was conducted as a part of a Locomotion Neuromechanics course (APPH 6232) offered in the School of Applied Physiology at Georgia Tech, https://en.wikipedia.org/w/index.php?title=Comparative_foot_morphology&oldid=991955698, Pages using columns with the default column width, Creative Commons Attribution-ShareAlike License, This page was last edited on 2 December 2020, at 18:29. This involved using evolutionary models to evaluate the relationship between foot bone proportions and the locomotory behaviour of monkeys and apes. The hind limb and foot of the elephant are oriented semi-plantigrade, and closely resemble the structure and function of the human foot. However, by aligning the hallux with the rest of the digits the connective tissues, tendons, ligaments and muscles of the foot are aligned to permit a longitudinal arch of the foot, integral for shock absorption during bipedal walking and running. In the horse, dryness of the hoof may cause stiffening of the external foot structure. The current inch and foot are implied from measurements in 12c." The tarsals and metapodials are arranged so as to form an arch, similarly to the human foot. There is virtually no give. N. Schmidt-Kittler, K. Vogel: Constructional Morphology and Evolution. Between the toes, the dorsal and plantar interossei stretch from the metatarsals to the proximal phalanges of digits two to five. The angled orientation of the elongated metatarsal and the digits extends the area available for storing and releasing mechanical energy in the muscle tendon units originating proximally to the ankle joint and terminating at the distal aspect of the foot bones. When standing, many terrestrial quadrupeds support more of their weight on their forelimbs rather than their hind limbs;[2][3] however, the distribution of body mass and limb loading changes when they move. [1] The expression to "...put one's foot in (one's) mouth "say something stupid" was first used in 1942. An individual who neutrally pronates initially strikes the ground on the lateral side of the heel. [13], Central muscle group: The four lumbricals arise on the medial side of the tendons of flexor digitorum longus and are inserted on the medial margins of the proximal phalanges. [10]. Flexor digitorum brevis flexes the middle phalanges. Skeletons of a human and an elephant. [12], Muscles of the little toe: Stretching laterally from the calcaneus to the proximal phalanx of the fifth digit, the abductor digiti minimi form the lateral margin of the foot and are the largest of the muscles of the fifth digit. The weight is distributed unevenly across the metatarsus, with excessive weight borne on the fifth metatarsal, towards the lateral side of the foot. [4][5][6] Humans have a lower-limb mass that is greater than their upper-limb mass. For example, High-heeled footwear are known to throw off the natural weight balance (this can also affect the lower back). In humans and elephants, a vertical-column orientation of the bones in the limbs and feet is also evident for associated skeletal muscle-tendon units. There can be many sesamoid bones near the metatarsophalangeal joints, although they are only regularly present in the distal portion of the first metatarsal bone. It is fully activated only with the knee extended, because the gastrocnemius is shortened during flexion of the knee. [6] The horse’s foot contains an external nail (hoof) oriented about the perimeter in the shape of a semicircle. An important plantar flexor, it is crucial to ballet dancing. Both the midfoot and forefoot constitute the dorsum (the area facing upwards while standing) and the planum (the area facing downwards while standing). In: Gould JA, Davies GJ, ed. [24] Foot disorders are common in captive elephants. Since there is no available dog doctor in your area please try some topical human cream or ointment which is available at a pharmacy for the human yeast infection of the toes and feet. As can be examined in a footprint, the medial longitudinal arch curves above the ground. As can be examined in a footprint, the medial longitudinal arch curves above the ground. They typically investigate to understand the nature of the pathology in order to generate and implement a clinical treatment plan. Some people consider it rude to wear shoes into a house and a Māori Marae should only be entered with bare feet. [18][19], The foot of the elephant possesses what is perhaps one of the most unusual distal cushions found in vertebrates. The forefoot also serves as a lever to allow balance during standing and jumping. The expression "...to put one's best foot foremost first recorded 1849 (Shakespeare has the better foot before, 1596)". Like an overpronator, an underpronator does not absorb shock efficiently – but for the opposite reason. Typical modern human robusticity pattern is 1>5>4>3>2, with a small percentage as 1>5>3>4>2. Because of the wide variety in body types, scaling and morphology of the distal limbs of terrestrial vertebrates, there exists a degree of controversy concerning the nature and organization of foot structures. The two long bones of the lower leg, the tibia and fibula, are connected to the top of the talus to form the ankle. Connected to the talus at the subtalar joint, the calcaneus, the largest bone of the foot, is cushioned underneath by a layer of fat. This greatly compromises arboreal abilities, since the foot cannot be used to grasp supports effectively. Abstract and Figures. The foot’s metatarsal robusticity pattern is similar to modern humans 1. In terms of age differences, older adults had shorter and stiffer feet. The hindfoot is the most proximal and posterior portion of the foot. An individual who overpronates tends to wear down their running shoes on the medial (inside) side of the shoe towards the toe area.[16]. [21] The horse hoof also acts dynamically during loading, which may cushion the endoskeleton from high loads that would otherwise produce critical deformation. [20] The cushions of the elephant's foot respond to the requirement to store and absorb mechanical loads when they are compressed, and to distribute locomotor loads over a large area in order to keep foot tissue stresses within acceptable levels. The plantaris originates on the femur proximal to the lateral head of the gastrocnemius and its long tendon is embedded medially into the Achilles tendon. The chief modifications are : (1) Gradual eversion of the foot, so that the sole can be applied to the ground. Extensor hallucis longus originates medially on the fibula and is inserted on the first digit. [5][11] Many of the aforementioned variables are connected with differences in the scaling of body and limb dimension as well as in patterns of limb coordination and movement. The forefoot (manus) and hindfoot (pes) contain huge pads of fat that are scaled to cope with the massive loadings imposed by the largest terrestrial vertebrate. Humans differ from all other primates in having nonopposable big toes (halluces). Neutral pronation is the most ideal, efficient type of gait when using a heel strike gait; in a forefoot strike, the body absorbs shock instead via flexation of the foot. Limb and foot structure of representative terrestrial vertebrates: There is considerable variation in the scale and proportions of body and limb, as well as the nature of loading, during standing and locomotion both among and between quadrupeds and bipeds. [6], Extensor group: the tibialis anterior originates on the proximal half of the tibia and the interosseous membrane and is inserted near the tarsometatarsal joint of the first digit. [24] The midfoot of the dog, horse and elephant contains similar intermediate structures having similar functions to those of the human midfoot. The underpronated foot is like a diving board that, instead of failing to spring someone in the air because it is too flimsy, fails to do so because it is too rigid. The distal phalanges of the elephant do not directly touch the ground, and are attached to the respective nail/hoof. The Foot Posture Index 9 was used to assess both feet of all participants. In contrast, the lateral longitudinal arch is very low. Because we focus on the foot, we do not directly cover the ankle (talocrural and subtalar joints), but we refer readers to Pontzer et al. Intrinsic Foot Muscle Morphology in Active Runners With and Without a History of Exercise-Related Lower Leg Pain in International Journal of Athletic Therapy and Training. As with a neutral pronator, an individual who overpronates initially strikes the ground on the lateral side of the heel. [1], The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments. One organizational approach to understanding foot structures makes distinctions regarding their regional anatomy. These muscle tendon unit structures appear well designed to aid in the ground-reaction transmission of forces that is essential for locomotion. [7], Peroneal group: the peroneus longus arises on the proximal aspect of the fibula and peroneus brevis below it. "Effects of mass distribution on the mechanics of level trotting in dogs", "Biomechanics of quadrupedal walking: how do four-legged animals achieve inverted pendulum-like movements? The metatarsal bones of feet and paws are tightly grouped compared to, most notably, the human hand where the thumb metacarpal diverges from the rest of the metacarpus. The structures in this region are intermediate in size, and typically transmit loads from the hindfoot to the forefoot. [1][13][14] In the dog and horse, the bones of the proximal limbs are oriented vertically, whereas the distal limb structures of the ankle and foot have an angulated orientation. Orthopaedic and Sports Physical Therapy. In the human and elephant, the bone structures contained in this region are generally longer and narrower. In the non-weight-bearing leg, the tibialis anterior dorsiflexes the foot and lift its medial edge (supination). Regarding bilateral asymmetry, the right foot had a higher foot than the left foot. The slight mobility of these arches when weight is applied to and removed from the foot makes walking and running more economical in terms of energy. [9] The locomotion of the elephant (which is the largest terrestrial vertebrate) displays a similar loading distribution on its hind limbs and forelimbs. Below its tendon, the tendons of the long flexors pass through the tarsal canal. ", "Ontogenetic scaling of foot musculoskeletal anatomy in elephants", "Joint Work and power for both the forelimb and hind limb during trotting in the horse", "Foot pressure distribution during walking in young and old adults", "The structure of the cushions in the feet of African elephants (Loxodonta Africana)", Philosophical Transactions of the Royal Society A, "Biomechanics of Foot Strikes & Applications to Running Barefoot or in Minimal Footwear", Biomechatronics Group Web Site Massachusetts Institute of Technology Media Lab, Dynamic Structure of the Human Foot. In anatomy, pronation is a rotational movement of the forearm (at the radioulnar joint) or foot (at the subtalar and talocalcaneonavicular joints). In the human and the elephant, the column orientation of the foot complex is replaced in humans by a plantigrade orientation, and in elephants by a semi-plantigrade alignment of the hind limb foot structure. [29] In the elephant, the nearly half-cupula-shaped arrangement of the bony elements of the metatarsals and toes has interesting similarities to the structure of the arches of human feet. In this approach, the foot may be described in three segments: as the hindfoot, midfoot and forefoot. For the sake of posture, flat soles with no heels are advised. Springer-Verlag, Berlin 1991, ISBN 3-540-53279-X. The two longitudinal arches serve as pillars for the transverse arch which run obliquely across the tarsometatarsal joints. The flexor digitorum brevis arises inferiorly on the calcaneus and its three tendons are inserted into the middle phalanges of digits two to four (sometimes also the fifth digit). [23] The hindfoot structures of the dog and horse are located relatively proximally compared to the elephant and human foot. The aim of this study was to explore the relationship between foot morphology and center-of-pressure excursion during barefoot walking. [1] The expression "put (one's) foot in something" meaning to "make a mess of it" was used in 1823. The flexor hallucis brevis arises on the medial cuneiform bone and related ligaments and tendons. The inside support area is marked by strong greyish material to support the weight when a person lands on the outside foot and then roll onto the inside foot. On the other hand, recent studies 2 suggest that the foot exhibits morphology indicative of longitudinal arch that is more like Homo. [1], The word "footloose" was first used in the 1690s, meaning "free to move the feet, unshackled"; the more "figurative sense of "free to act as one pleases" was first used in 1873. It is occasionally absent. Results: Compared with females, males had longer, larger and higher feet. In this configuration, the foot is able to absorb and damp the large loads encountered during heel strike and early weight acceptance. b. ... gave written informed consent before testing in accordance with the requirements of The University of Sydney human ethics committee. [6] When muscle tendon units lengthen, the load strain facilitates mechanical activity. [12] Humans possess a tough fibro and elastic pad of fat that is anchored to the skin and bone of the rear portion of the foot. The underlying bones are arranged in a semi-vertical orientation. … The peroneus longus also acts like a bowstring that braces the transverse arch of the foot. An individual whose bone structure involves external rotation at the hip, knee, or ankle will be more likely to overpronate than one whose bone structure has internal rotation or central alignment. [7][8][12] In the human, the structures of the hand are generally similar in shape and arrangement to those of the foot. As the individual transfers weight from the heel to the metatarsus, the foot will roll in a medial direction, such that the weight is distributed evenly across the metatarsus. The popliteus is also part of this group, but, with its oblique course across the back of the knee, does not act on the foot. Aliza K. Nedimyer MA, LAT, ATC * , 1 , Brian G.

While human sexual dimorphism is generally expected to be the result of differential reproductive strategies, it has the potential to create differences in the energetics of locomotion and the speed at which each morph travels, particularly since people have been shown to choose walking speeds around their metabolic optimum. Umfangreiche Liste von Publikationen zur Konstruktions-Morphologie. [31], The unique plantigrade alignment of the human foot results in a distal-limb structure that can adapt to a variety of conditions. Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables. [20], The word "foot" is used to refer to a "...linear measure was in Old English (the exact length has varied over time), this being considered the length of a man's foot; a unit of measure used widely and anciently. Human foot inversion prior to toe-off: an analysis by means of functional morphology, and comparative anatomical observation. This is apparent in the human and elephant foot, where the hindfoot undergoes greater loading during initial contact in many forms of locomotion. For instance, it may provide insights that make it possible to alter the foot's load transmission in people who wear an external orthosis because of paralysis from spinal-cord injury, or who use a prosthesis following the diabetes-related amputation of a leg. Distally, the peroneus longus crosses the plantar side of the foot to reach its insertion on the first tarsometatarsal joint, while the peroneus brevis reaches the proximal part of the fifth metatarsal. [11] Similar to the intrinsic muscles of the hand, there are three groups of muscles in the sole of foot, those of the first and last digits, and a central group: Muscles of the big toe: the abductor hallucis stretches medially along the border of the sole, from the calcaneus to the first digit. The abductor hallucis is an abductor and a weak flexor, and also helps maintain the arch of the foot. [22] Functionally, the structures contained in this region are typically robust, possessing a larger size and girth than the other structures of the foot. [8], The superficial layer of posterior leg muscles is formed by the triceps surae and the plantaris. The hind limbs of the dog and horse have a slightly greater mass than the forelimbs, whereas the elephant has proportionally longer limbs. Its strength becomes most obvious during ballet dancing. Experimental Procedures . Similar characteristic features emerge in the human foot in the form of the pes cavus alignment deformity, which is produced by tight connective tissue structures and joint congruency that create a rigid foot complex. Terrestrial vertebrate quadrupeds and bipeds generally possess distal limb and foot endoskeleton structures that are aligned in series, stacked in a relatively vertical orientation and arranged in a quasi-columnar fashion in the extended limb. In the US this condition is called: Athletes foot. The foot can be subdivided into the hindfoot, the midfoot, and the forefoot: The hindfoot is composed of the talus (or ankle bone) and the calcaneus (or heel bone). The stiffer hoof reduces the foot's load attenuation capacity, rendering the horse unable to bear much weight on the distal limb. There are a number of contexts where it is considered inappropriate to wear shoes. The paper illustrates the effect of linear scaling of the first, second and fifth digit lengths upon forefoot … The human foot has been highly modified for upright progression. This rolling inwards motion as the foot progresses from heel to toe is the way that the body naturally absorbs shock. The characteristics of foot morphology were measured using a 3D foot scanner. The legged locomotion of humans generally distributes an equal loading on each lower limb. The branch of biology that deals with the form and structure of organisms without consideration of function. Foot Morphology. Sweat itself is odorless, but it creates a beneficial environment for certain bacteria to grow and produce bad-smelling substances. The word "foot", in the sense of meaning the "terminal part of the leg of a vertebrate animal" comes from "Old English fot "foot," from Proto-Germanic *fot (source also of Old Frisian fot, Old Saxon fot, Old Norse fotr, Danish fod, Swedish fot, Dutch voet, Old High German fuoz, German Fuß, Gothic fotus "foot"), from PIE root *ped- "foot." Foot sweat is the major cause of foot odor. This suggests that the Neanderthal-specific characters of the phalanx evolved after the divergence of Denisovans … [1] The slight mobility of these arches when weight is applied to and removed from the foot makes walking and running more economical in terms of energy. [1] An overpronator does not absorb shock efficiently. forces that shaped human foot anatomy, and more broadly the evolution of bipedalism. Homo erectus gilt als die erste Art der Gattung Homo, die sich weit über Afrika hinaus verbreitete. They act to dorsiflex the digits. The extensor digitorum longus acts similar to the tibialis anterior except that it also dorsiflexes the digits. Similarly, the cushioned frog situated centrally at the rear ends of the hoof undergoes compression during loading, and expansion when unloaded. Diese etablierte Annahme wurde nun von israelischen Wissenschaftlern in ihrem Artikel "Revised estimates for the number of human and bacteria cells in the body" widerlegt. In this stage of the gait, the knee will generally, but not always, track inwards. Similarly, an overpronator's arches will collapse, or the ankles will roll inwards (or a combination of the two) as they cycle through the gait. Die Palichnologie (seltener auch Paläoichnologie; griech. The elephant's forelimbs are longer than its hind limbs.[7]. The joints between the phalanges are called interphalangeal and those between the metatarsus and phalanges are called metatarsophalangeal (MTP).[2]. The paw of the dog, the hoof of the horse, the manus (foot) and pes (foot) of the elephant, and the foot of the … Similar to the fingers of the hand, the bones of the toes are called phalanges and the big toe has two phalanges while the other four toes have three phalanges each. [2], The five irregular bones of the midfoot, the cuboid, navicular, and three cuneiform bones, form the arches of the foot which serves as a shock absorber. An individual who underpronates also initially strikes the ground on the lateral side of the heel. The comparative morphology of the distal limb and foot structure of some representative terrestrial vertebrates reveals some interesting similarities. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates. Their foot structures function as the load-transmission platform which is essential to balance, standing and types of locomotion (such as walking, trotting, galloping and running). [2] The joints of the foot are the ankle and subtalar joint and the interphalangeal articulations of the foot. As the individual transfers weight from the heel to the metatarsus, the foot will not roll far enough in a medial direction. Depending on style of locomotion, animals can be classified as plantigrade (sole walking), digitigrade (toe walking), or unguligrade (nail walking). [17] The forefoot, with its long metatarsal and relatively long phalanges, transmits loads during the end-of-stance phase that facilitate the push-off and transfer of forward momentum. Also, the wearing of shoes, sneakers and boots can impede proper alignment and movement within the ankle and foot. In this stage of the gait, the knee will generally, but not always, track directly over the hallux. In addition, there are several genetic disorders that can affect the shape and function of the feet, including a club foot or flat feet. The columnar orientation of bones and connective tissue is similarly well-aligned to transmit loads during the weight-bearing phase of locomotion. The metatarsals are the bones that make up the main part of the foot in humans, and part of the leg in large animals or paw in smaller animals. This leaves humans more vulnerable to medical problems that are caused by poor leg and foot alignments. An anthropometric study of 1197 North American adult Caucasian males (mean age 35.5 years) found that a man's foot length was 26.3 cm with a standard deviation of 1.2 cm.[3]. Heute werden zahlreiche Fossilienfunde dem Homo erectus zugeordnet, die von ihren Entdeckern zunächst eigene Gattungs- und Artnamen erhalten hatten, so zum Beispiel der von Eugène Dubois benannte Anthropopithecus („Java-Mensch“), der von Davidson Black benannte Sinanthropus pekinensis („Peking-Mensch“), der von John T. Robinson benannte Telanthropus capensis („Zielmensch“, ein Fund aus Swart… It is usually visible. Both heads are inserted into the lateral sesamoid bone of the first digit. Konstruktions-Morphologie am Forschungsinstitut und Naturmuseum Senckenberg [28] The distal cushion is highly innervated by sensory structures (Meissner's and Pacinian corpuscles), making the distal foot one of the most sensitive structures of the elephant (more so than its trunk). These tendons divide before their insertions and the tendons of flexor digitorum longus pass through these divisions. The paw of the dog, the hoof of the horse, the manus (foot) and pes (foot) of the elephant, and the foot of the human all share some common features of structure, organization and function. Such knowledge can be incorporated in technology that improves a person's balance when standing; enables them to walk more efficiently, and to exercise; or otherwise enhances their quality of life by improving their mobility. Imagine someone jumping onto a diving board, but the board is so flimsy that when it is struck, it bends and allows the person to plunge straight down into the water instead of back into the air. A hard foot is called a hoof. Seit 1972 gilt die Faustregel, dass im Menschen die Anzahl von bakteriellen und menschlichen Zellen im Verhältnis 10:1 steht. The human transverse tarsal joint of the midfoot transmits forces from the subtalar joint in the hindfoot to the forefoot joints (metatarsophalangeal and interphalangeal) and associated bones (metatarsals and phalanges). The instep is the arched part of the top of the foot between the toes and the ankle. They found that this sixth toe acts to support and distribute the weight of the elephant. (2014), O’Neill et al. The tarsals of the midfoot, which are smaller and shorter than the hindfoot tarsals, appear well oriented to transmit loads between the hindfoot and forefoot; this is necessary for load transfer and locking of the foot complex into a rigid lever for late stance phase. All muscles originating on the lower leg except the popliteus muscle are attached to the bones of the foot. Weblinks. However, little is understood concerning the functional contribution of the foot and its structures during the weight-bearing phase. [20], The distal cushions of all these organisms (dog, horse, human and elephant) are dynamic structures during locomotion, alternating between phases of compression and expansion; it has been suggested that these structures thereby reduce the loads experienced by the skeletal system.[18][19][20][21]. In this sense the plural is often foot. Veterinarian or human healthcare professionals often respond when the foot of a dog, horse, elephant or human develops an abnormality. The forefoot represents the most distal portion of the foot. Individuals with pes cavus display characteristic reduced load-attenuation features, and other structures proximal to the foot may compensate with increased load transfer (i.e., excessive loading to the knees, hips, lumbo-pelvic joints or lumbar vertebrae).
