[1] [2] The phalanges of the hand are commonly known as the finger bones. The phalanges of the foot differ from the hand in that they are often shorter and more compressed, especially in the proximal phalanges, those closest to the torso. [3] A phalanx is named according to whether it is proximal, middle, or distal and its associated finger or ...
the plantar region encompassing the sole of the foot. Some regions are combined into larger regions. These include the trunk, which is a combination of the thoracic, mammary, abdominal, navel, and coxal regions. The cephalic region is a combination of all of the head regions. The upper limb region is a combination of all of the arm regions. The ...
Reptiles usually retain two centralia, while mammals typically have only one (the navicular). [ 3 ] In birds, the tarsus has disappeared, with the proximal tarsals having fused with the tibia, the centralia having disappeared, and the distal bones having fused with the metatarsals to form a single tarsometatarsus bone, effectively giving the ...
In this approach, the foot may be described in three segments: as the hindfoot, midfoot and forefoot. The hindfoot is the most proximal and posterior portion 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.
The foot (pl.: feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion . In many animals with feet, the foot is a separate [ clarification needed ] organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.
The palmar fascia is palmar to the tendons of muscles which flex the fingers, and the dorsal venous arch is so named because it is on the dorsal side of the foot. In humans, volar can also be used synonymously with palmar to refer to the underside of the palm, but plantar is used exclusively to describe the sole.
The first metatarsal bone is the bone in the foot just behind the big toe. The first metatarsal bone is the shortest of the metatarsal bones and by far the thickest and strongest of them. [1] Like the four other metatarsals, it can be divided into three parts: base, body and head.
Its plantar surface is grooved antero-posteriorly for the passage of the flexor tendons, and marked on either side by an articular eminence continuous with the terminal articular surface. [ 4 ] During growth, the growth plates are located distally on the metatarsals, except on the first metatarsal where it is located proximally.
