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

Author(s): Shikha Saini and Shailja Bansal
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).
