What is the glenoid fossa?
The glenoid fossa is the socket of the shoulder joint. This part of the shoulder is a ball and socket joint. The head of the Humerus fits into the Glenoid fossa, though it is a shallow socket.
What is a glenoid in the shoulder?
The end of the scapula, called the glenoid, meets the head of the humerus to form a glenohumeral cavity that acts as a flexible ball-and-socket joint. The joint is stabilized by a ring of fibrous cartilage surrounding the glenoid, called the labrum.
What structures help stabilize the shoulder joint?
The ligaments in the shoulder are all named after the bones they connect. The clavicle has two ligaments involving the shoulder that help with stabilizing it to nearby bony structures: The acromioclavicular ligament and the coracoclavicular ligament both stabilize the clavicle to the shoulder blade.
What are the 4 joints in the shoulder?
Four joints are present in the shoulder: the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints, and glenohumeral joint.
Why is the shoulder joint stable?
Sockets capsules ligaments We have found that glenohumeral stability requires that there be a socket into which the ball can be pressed and that the muscles around the joint work in a balanced way to press the humeral head into the glenoid (see figures 4 and 5).
Is the shoulder joint stable?
The shoulder is our most mobile, yet least stable joint. Its tremendous range of motion makes the shoulder less stable, and it is generally more prone to injury and dislocation than our other joints.

What are the most freely movable joints in the body?
A synovial joint, also known as a diarthrosis, is the most common and most movable type of joint in a mammal’s body. Diarthroses are freely movable articulations.
What are the least movable joints?
Immovable or fibrous joints are those that do not allow movement (or allow for only very slight movement) at joint locations. Bones at these joints have no joint cavity and are held together structurally by thick fibrous connective tissue, usually collagen.
What is the name for freely movable joints?
Diarthroses
