Proximal interphalangeal region

In Horses, Donkeys and Ruminants, the long pastern bone (Compes) corresponds to the region of the proximal phalanx (Regio phalangis proximalis) called the compedal region (Regio compedis).; it is shrunk in its middle; its palmar surface, that is overlooked by the spur and the dewlap, presents the pastern fold.
