Anatomical terms of bone

The lateral angle of the scapula (head of the scapula) is the thickest part of the bone.

On it is a shallow pyriform, articular surface, the glenoid cavity, which is directed lateralward and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.

The surface is covered with cartilage in the fresh state; and its margins, slightly raised, give attachment to a fibrocartilaginous structure, the glenoidal labrum, which deepens the cavity.

At its apex is a slight elevation, the supraglenoid tuberosity, to which the long head of the Biceps brachii is attached.

The neck of the scapula is the slightly constricted portion which surrounds the head; it is more distinct below and behind than above and in front.
