The foot comprises three parts: seven tarsal bones (A-E), five metatarsals (F),and fourteen phalanges(G). The tarsal bones include the ankle, heel, and instep. The metatarsals are longer and stronger than the five metacarpals of the hand, and they end at the ball of the foot. The phalanges of the fingers and thumb; the four small toes press and grip the ground surface, and the big toe tends to have a slight up ward thrust.

When the foot is flexed upward, these tendons are evident: extensor digitorum longus (1), extensor digitorum brevis (2), tibialis anterior (3), and extensor hallucis longus (4).
