What is the infraspinous fossa?

Explanation:
Fossa means a hollow or shallow basin on a bone. On the scapula, the posterior surface is divided by the spine into two fossae: above the spine is the supraspinous fossa, below the spine is the infraspinous fossa. The infraspinous fossa is a broad, concave area located beneath the scapular spine, serving as the attachment site for the infraspinatus muscle. That makes it the hollow, depressed area under the scapular spine. The other descriptions don’t fit: a generic “space behind the scapula” is vague, a “groove” implies a sulcus, and “space above the scapula” would be the supraspinous fossa, not the infraspinous fossa.
