Three phalanges are present on each finger and toe, with the exception of the thumb and big toe, which possess only two.

Medial epicondyle of the humerus (common flexor tendon) as well as parts of the radius and ulna: Insertion: Anterior margins on the base of the middle phalanges of the four fingers: Artery: Radial artery: Nerve: Median nerve: Actions: Flexor of fingers (primarily at proximal interphalangeal joints) Antagonist: Extensor digitorum muscle ...
Feet and ankles (52 bones) - Left and right tarsals (14) (ankle), metatarsals (10) (foot), proximal phalanges(10), intermediate phalanges (8) and distal phalanges (10) .
