Abstract :

 Sloth bear is one of the youngest carnivores occupying a wide range of habitats in Indian subcontinent. Carcass of sloth bears were studied from Bannerghatta Bear Rescue Centre, Bangalore. The study was undertaken to systematically establish the myological characteristics of shoulder region muscle which might help to carryout morphological assessments. In this study it was observed that well developed supraspinous fossa was filled by M. supraspinatus and infraspinous fossa was filled by M. infraspinatus. The powerful deltoideus muscle consisted of two bellies, arose from acromion process and from the fascia overlying M. infraspinatus. Subscapularis muscle was divided into five fascicular tracts and additional subscapularis minor muscle which was positioned medial to M. subscapularis proper. M. coracoachialis consisted of two heads, short head inserted beneath the lesser tubercle and longus inserted on supracondylar crest. In sloth bear attachment of muscle was more proximally compared with other carnivore which may account for slow gait of bears and the muscle mass has reflected the quadrupedal walking of sloth bear.
