Fingers of hand
Digiti manus
Definition
Each finger presents a dorsal surface (Facies dorsalis), a plantar surface (Facies plantaris) that is concave in direction of the fexion, an axial surface (Facies axalis) turned in direction of the axis of the foot and an abaxial surface (Facies abaxialis) turned to the opposite side (In Equidae, these surfaces are simply called medial and lateral).
The topographic subdivisions of the fingers of the Ruminants, Horses and Donkeys, because of their volume, received a particular name. In a proximodistal direction, we find
-the carpus,
-the cannon bone (Third metacarpal),
-the fetlock (Metacarpophalangeal joint),
-the long pastern bone (Proximal phalanx),
-the pastern joint (Proximal interphalangeal joint),
-the short pastern bone (Middle phalanx),
-the coffin joint (Distal interphalangeal joint),
-and the coffin bone (Distal phalanx)
