The metatarsal bones or metatarsus (pl.: metatarsi) are a group of five long bones in the midfoot, located between the tarsal bones (which form the heel and the ankle) and the phalanges . Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe ): the first , second , third , fourth , and fifth ...
The fifth metatarsal bone is a long bone in the foot, and is palpable along the distal outer edges of the feet. It is the second smallest of the five metatarsal bones. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand. [1] As with the four other metatarsal bones it can be divided into three parts; a base, body and head.
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.
The bones entering into their formation are the first, second, and third cuneiforms, and the cuboid bone, which articulate with the bases of the metatarsal bones. The first metatarsal bone articulates with the first cuneiform; the second is deeply wedged in between the first and third cuneiforms articulating by its base with the second ...
The transverse arch is composed of the three cuneiforms, the cuboid, and the five metatarsal bases. The transverse arch is strengthened by the interosseous, plantar, and dorsal ligaments, by the short muscles of the first and fifth toes (especially the transverse head of the adductor hallucis ), and by the fibularis longus , whose tendon ...
In the wrist—The pisiform of the wrist is a sesamoid bone (within the tendon of flexor carpi ulnaris). [8] It begins to ossify in children ages 9–12. [9] In the foot—the first metatarsal bone usually has two sesamoid bones at its connection to the big toe (both within the tendon of flexor hallucis brevis). [10]
The fourth metatarsal bone is a long bone in the foot. It is smaller in size than the third metatarsal bone and is the third longest (and smallest) of the five metatarsal bones. The fourth metatarsal is analogous to the fourth metacarpal bone in the hand [1] As the four other metatarsals bones it can be divided into three parts; base, body and ...
The third metatarsal is analogous to the third metacarpal bone in the hand [1] Like the four other metatarsal bones, it can be divided into three part: base, body and head. The base is the part closest to the ankle and the head is closest to the toes. The narrowed part in the middle is referred to as the body of the bone.
