The proximal phalanx bone of each toe articulates with the metatarsal bone of the foot at the metatarsophalangeal joint. Each toe is surrounded by skin, and present on all five toes is a toenail. The toes are, from medial to lateral: the first toe, also known as the hallux ("big toe", "great toe", "thumb toe"), the innermost toe;
They are analogous to the knuckles of the hand, and are consequently known as toe knuckles in common speech. They are condyloid joints, meaning that an elliptical or rounded surface (of the metatarsal bones) comes close to a shallow cavity (of the proximal phalanges). The region of skin directly below the joints forms the ball of the foot.
The function of the muscle is to move the fourth toe medially and move the toes together. [ 2 ] The horizontal head of the adductor hallucis also originates from the lateral side of the metacarpophalangeal joint and from the deep transverse metatarsal ligament , [ 2 ] a narrow band which runs across and connects together the heads of all the ...
The second and third metatarsals are fixed while walking, thus these metatarsals are common sites of injury. The fifth metatarsal may be fractured if the foot is oversupinated during locomotion. [9] Protection from injuries can be given by the use of safety footwear which can use built-in or removable metatarsal guards.
Morton's toe is the condition of having a first metatarsal bone that is shorter than the second metatarsal (see diagram). It is a type of brachymetatarsia. [1] This condition is the result of a premature closing of the first metatarsal's growth plate, resulting in a short big toe, giving the second toe the appearance of being long compared to the first toe.
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 interphalangeal joints of the foot are the joints between the phalanx bones of the toes in the feet. Since the great toe only has two phalanx bones ( proximal and distal phalanges), it only has one interphalangeal joint, which is often abbreviated as the " IP joint ".
The third metatarsal bone is a long bone in the foot. It is the second longest metatarsal, the longest being the second metatarsal. 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.
