The little toe is also known is the fifth digit of the foot. It is the smallest and weakest of all five digits. Still, like other toes, it assists the foot while walking, jogging and other bipedal movements. In some cases, people have been born with congenital deformities where either a digit in the foot is missing, or a sixth toe is evident. In such rare cases, the designation of "little toe" may shift from the fifth to the sixth digit. The little toe comprises of the three phalangeal bones. These include a proximal, intermediate and distal phalanx. The proximal bone articulates the fifth metatarsal of the foot, and the intermediate phalanx articulates with its distal and proximal counterparts. The fifth digit is served oxygenated blood from a branch of the plantar arch. Two muscles serve the digit, which include the flexor and abductor digiti minimi muscles. In this two, innervations are supplied by the lateral plantar nerve and its superficial branch.
