Rear View Of The Supraspinous Fossa Of The Scapula

Description

Posteriorly, the scapular spine runs transversely as a sharp ridge, separating the supraspinous fossa superiorly from the broader infraspinous fossa inferiorly. Across the sequence, the animation holds a rear view while subtly rotating the shoulder blade (scapula) to clarify the triangular contour of the supraspinous fossa, the medial border leading toward the superior angle and the lateral margin tapering into the root of the spine near the acromion. The suprascapular notch at the superior border sits anterosuperior to this depression, while the glenoid cavity remains lateral and slightly anterior, only hinted at by the scapular neck’s contour. Bony landmarks read cleanly. This region matters because the supraspinous fossa houses the supraspinatus muscle, whose tendon passes beneath the acromion to insert on the greater tubercle of the humerus, a frequent site of rotator cuff tendinopathy and full-thickness tears. Seeing the scapular spine and fossa boundaries in motion helps learners avoid common orientation errors when correlating posterior surface anatomy with ultrasound probe positioning, MRI planes, or arthroscopic portals at the posterior shoulder. The relationship between the fossa and the acromial end of the scapular spine also frames discussion of subacromial impingement and the narrow space traversed by the supraspinatus tendon. Use this animation in gross anatomy lab orientation, musculoskeletal radiology teaching files, and surgical education modules introducing rotator cuff anatomy and posterior scapular landmarks. It also fits orthopedic and sports medicine presentations where you need a quick, accurate refresher on scapular topography before discussing tear patterns or rehabilitation mechanics.
