Scapula (left & right)

(Lateral view)

The spine of the scapula divides the lateral surface into the anterior supraspinous fossa and the posterior infraspinous fossa.

The acromion is a finger-like extension of the spine that points ventrally. The larger metacromion extends to the posterior. These two processes are important sites for muscle attachment.
