Foot bones and cartilage. Artwork of the bones and cartilage (white, ends of bones) of the foot and the ankle joint from the side. This is a lateral view of the outside of the foot. The human foot contains 26 bones. Seven of these form the tarsus (lower right, including the calcaneus, the heel bone) between the bones of the lower leg and the rest of the foot. The lower leg bones (upper right) are the tibia (thicker bone) and the fibula. From the tarsus the five metatarsals of the foot join to the phalanges (toe bones). The big toe has two phalanges, while the other toes have three. For a sequence showing foot anatomy, see C016/7008 to C016/7010.
