Gross anatomical studies on the pectoral girdle and wings of Emu (Dromaius novaehollandiae)
Rajalakshmi K, Sridevi P and Siva Kumar M
In the present study, pectoral limb was formed by scapulo- coracoid and clavicle. The scapula and coracoid fused at the junction of the glenoid cavity to form a single bone called scapulo coracoid. The clavicles were short, flat to rounded rod like bone. The glenoid cavity was a concave articular cavity formed by both scapula and coracoid. The clavicles did not participate in formation of glenoid cavity. Humerus was a strong cylindrical and the Proximal extremity consisted of an indistinct head, neck and two tuberosities lateral and medial. Distal extremity presented a sulcus on the anterior surface. The radius was slender and rod like were almost equal in length but shorter than the humerus. The radius and ulna enclosed a wide interosseous space. There were two carpals in the proximal row radial and ulnar. The radial carpal was partially fused with the radius and also articulated with the ulna while its distal end was fused with the carpometacarpus.
