Toe

Toes are the digits of the foot of a tetrapod. Animal species such as cats that walk on their toes are described as being digitigrade. Humans, and other animals that walk on the soles of their feet, are described as being plantigrade; unguligrade animals are those that walk on hooves at the tips of their toes. The toes are, from medial to lateral:

The human foot consists of numerous bones and soft tissues which support the weight of the upright human. Specifically, the toes assist the human while walking, providing balance, weight-bearing, and thrust during the gait.

Humans typically have five toes on each foot. Exceptions include polydactyly (more than five toes), and syndactyly or amputation (fewer than five toes). The four smallest toes consist of three phalanx bones, while the largest consists of two phalanx bones and two sesamoid bones. Many of the flexor tendons are shared, making it impossible to move individual toes independently; however, some prehensility, or grasping capability, does exist for most humans.
