Anatomy of the humerus of nilgai (Boselaphus tragoeamalus)

Abstract

This study was conducted on humerii of an adult male nilgai. The shaft of the humerus was bent latero-medially and twisted on appearance. The anterior surface of the shaft-presented longitudinal muscular imprints on its proximal broad part and distal narrow part. The teres tubercle was placed above the middle point of the medial surface and its was very rough. A well developed ridge extended from the teres tubercle to meet the margin of the head of humerus. The musculo spiral groove was well developed and deep. Similarly the deltoid tuberosity was massive and elongated in shape. The round module for insertion of teres minor muscle was less developed. The lateral tuberosity of the proximal extremity was divided into an anterior small tubercular part and a posterior roughly quadrilateral part. The bicipital groove was deep and wide. The medial margin of the radial fossa was erect like and sharp pointed. The lateral margin of the lateral epicondyle was rough and become projected towards the anterior surface. The axial margins of the distal extremity of both the epicondyle were pointed./p>
