The sides of the bases of metatarsals II to V also articulate with each other. The lateral side of the base of metatarsal V has a prominent tuberosity, which projects posteriorly and is the attachment site for the tendon of the fibularis brevis muscle.
The phalanges are the bones of the toes (Fig. 6.100). Each toe has three phalanges (proximal, middle, and distal), except for the great toe, which has only two (proximal and distal).
