In mammals like rabbit, each half of pectoral girdle consists of 3 bones. Each half of the girdle mainly comprises a large, flattened and triangular cartilage bone, the scapula (shoulder blade), whose broader side is dorsal and narrower side ventral. The dorsal margin is bordered by a narrow strip of cartilage called suprascapula. At the narrow end, the scapula is itself fused with an inwardly bent, knob-like coracoid process.
