Gross anatomy of the skeleton of pectoral limb in Indian eagle owl (Bubo bengalensis)

Author(s): Shikha Saini and Shailja Bansal
Abstract:
The gross anatomy of bones of the wing was studied in Indian eagle owl. The shoulder girdle comprised of three bones i.e., scapula, coracoid and clavicle. Scapula was sword-like bone and its proximal extremity presented an acromion process and a coracoid process. The coracoid with its spatula-shaped distal end was the strongest bone of the shoulder girdle. The right and left clavicle fused distally to form a single ‘V’ shaped bony mass - the furcula. These three bones enclosed the foramen triosseum which allows the passage of tendon of flight muscles. Humerus was a strong cylindrical bone with a proximal extremity having head, lateral tubercle, and medial tubercle and distal extremity having ulnar and radial condyles, respectively. The radius was a long, rod-like bone with slightly curved shaft. Ulna was of almost equal length to radius. Its proximal extremity was expanded and presented the olecranon process and distal extremity presented a small condyle. The cylindrical shaft was fused with the radius thereby, enclosed a wide interosseous space between them. The carpus was comprised of two bones – radial and ulnar carpal bones. The carpometacarpal was formed by the fusion of the distal row of carpal bones and proximal extremity of the metacarpus. There were three carpometacarpals – major, minor and the alular carpometacarpus. Three digits (Digiti manus) were observed – digit-I (comprised of first phalanx only), digit-II (comprised of two phalanges), and digit- III (comprised of only one phalanx).
