The joints anatomical description highlights the standards for biomechanical conditions that must be considered in the selection of a particular animal species. Thus, the objective was to describe the metacarpal phalangeal joint in sheep, for its architecture and adjacent structures. For this purpose, we used ten adult sheep, Santa Ines breed, males and females, randomly chosen. The anatomical specimens for the study were collected by the disarticulation of the distal row of carpal and metacarpal bone of an sheep's forelimb. To observe the joint capsule, adjacent structures were overruled and their topographical relationships with such joint analyzed. The longitudinal measures of the joint capsule and the III-IV metacarpal bones, proximal phalanges III and IV proximal phalanx were taken. Through the results, it is concluded that the metacarpal phalangeal joint in sheep presents similar topographical relationships described for other ruminants, with connections at the proximal and recesses at the distal areas.
