Step-by-step solution
The last 2 pairs (11 th and 12 th ) of ribs are not connected ventrally to the sternum and are, therefore, called floating ribs. Each half of the pectoral girdle consists of a clavicle and a scapula. The scapula is a large triangular flat bone situated in the dorsal part of the thorax between the second and the seventh ribs. The dorsal, flat, triangular body of the scapula has a slightly elevated ridge called the spine which projects as a flat, expanded process called the acromion which forms the highest point of s
