Strengthens the superior portion of the joint capsule. It runs from the lateral border of the root of the coracoid process to the anterior border of the greater tubercle. It is superficial to the tendon of the long head f the biceps. It helps to prevent inferior subluxation of the humeral head. Bursae contain synovial fluid.
Inflammation leads to bursitis.
The subacromial protects the supraspinatus tendon. Subacromial bursa, Supraspinatus tendon, Glenohumoral joint capsule, Biceps long head tendon. The greater tubercle of the humerus comes in contact with the acromion during abduction of the arm putting pressure on the contents of the subacromial space. If one externally rotates the arm during abduction, the greater tubercle is moved posteriorly and will not impinge as much on the structures in the subacromial space. Name the parts of a typical rib.
