Study Notes
Shoulder Joint
- The shoulder joint is a ball-and-socket joint.
Formation of the Shoulder Joint
- The shoulder joint is formed by the articulation of two bones: the humerus (upper arm bone) and the scapula (shoulder blade).
Glenoid Fossa
- The glenoid fossa is made deeper by the presence of the glenoid labrum, a ring of cartilage that surrounds the fossa.
Glenoid Labrum and Associated Muscles
- The tendon of the long head of the biceps brachii muscle is continuous with the glenoid labrum above.
Subacromial Space
- A subacromial space less than 6 mm in middle age can be a sign of rotator cuff disease or tendinopathy.
