Spine of scapula

The spine of the scapula extends on the lateral surface of the scapula from the dorsal border to the ventral angle, increasing in height dorsoventrally.

The spine of the scapula ends with the acromion, a well-defined eminence, located close to the ventral angle in carnivores and ruminants but remaining distal in pigs and horses. The acromion extends ventrally in carnivores (hamate process) and extends caudally in felidae (suprahamate process). The rabbits possess the both processes of acromion (hamate and suprahamate).
