Glenohumeral (shoulder) joint

Watch videos

The glenohumeral joint, also known as the shoulder joint, is a ball-and-socket type of synovial joint, in which the head of the humerus (ball) articulates with the glenoid fossa of the scapula (socket). The surface of the humeral head is much larger than the surface of glenoid fossa, which allows for the greatest range of motion seen in any joint. This mobility comes at the cost of joint stability, with the shoulder joint being one of the most frequently dislocated joints of the body. Watch the following video to learn about the anatomy of the shoulder joint, its associated ligaments and muscles, and its functions.

Once you mastered the basics about the shoulder joint, watch the next video to learn about the main muscles that stabilize and provide movements to the shoulder joint.
