Fingers and toes represent the masterful engineering of mother nature found in human and primate anatomy. For simplicity, toes are the focus today, but their design is alike.
Toes are made up of three bones called phallanges (sing. phallanx), except the hallux or big toe, which only has two. Where the toe meets the foot forms a "knuckle." Thus, the average toe has three knuckles, one nearest the foot, one further away, and one in the middle.
