The dorsal ligaments are strong, flat bands.. The first metatarsal is joined to the first cuneiform by a broad, thin band; the second has three, one from each cuneiform bone; the third has one from the third cuneiform; the fourth has one from the third cuneiform and one from the cuboid; and the fifth, one from the cuboid.
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.
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.
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.
Human toes A woman's toes decorated with nail polish and henna, and wearing a metti on the second toe, for her wedding There are normally five toes present on each human foot. Each toe consists of three phalanx bones , the proximal, middle, and distal , with the exception of the big toe ( Latin : hallux ).
However, human feet, and the human medial longitudinal arch, differ in that the anterior part of the foot is medially twisted on the posterior part of the foot, [12] so that all the toes may contact the ground at the same time, and the twisting is so marked that the most medial toe, the big toe or hallux, (in some individuals the second toe ...

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 ...
