The objective of this study was to establish the functional characteristics of forelimb muscle of sloth bear. In sloth bear, scapular muscles had long fascicle followed by fore arm and manus muscles. There was a signicant reduction in muscle mass distribution from proximal to distal portion.In shoulder and arm region, physiological cross sectional area (PCSA) was greater in proximal than distal muscle group, particularly in the shoulder extensors and elbow extensors. In forearm and manus region, it was greater in caudomedial aspect of muscles particularly in the pronators of forearms and exors of manus. Hence, it enabled greater grip strength

Key Words: Functional specialization, forelimb, Sloth bear
