The shoulder joint is considered a ball and socket joint.

Labrum anatomy. The term labrum is used in anatomy to designate a lip edge or brim. The outer glenoid is vascular and the inner glenoid is avascular 4. The anterior portion is most vulnerable when the labrum tears.

The labrum surrounding the shoulder socket is called the the glenoid labrum. The glenoid labrum is approximately 4 mm thick and is round or triangular in cross section. It contributes to shoulder stability and when torn can lead to partial or complete shoulder dislocation.

It is triangular in cross section. The acetabular labrum is a ring of cartilage that surrounds the acetabulum of the hip. Circumferentially orientated layer with radial reinforcing filaments.

Keeping joint fluid inside the hip joint capsule joint fluid. One arm of the biceps tendon long head also attaches to the shoulder labrum at its top. Helping maintain alignment between the hips ball and socket.

Glenoid labrum gross anatomy. It acts and looks almost like a washer sealing the two sides of the joint together. It is a fibro cartilaginous rubbery structure which encircles the glenoid cavity deepening the socket providing static stability to the glenohumeral joint.

The labrum is the attachment site for the ligaments and supports the ball and socket joint along with the rotator cuff tendons and muscles. The labrum is a thick fibrous ring that surrounds the glenoid. It helps provide stability to the shoulder by deepening the socket and serving as a firm attachment point for the ligaments that connect the humerus to the glenoid.

It coats the surface of the socket area with a soft cartilage enabling the shoulder to move more freely and painlessly. The glenoid labrum is similar to the meniscus of the knee. The labrum serves several purposes including.

The labrum is thickest posterosuperiorly and widest anterosuperiorly. The term labrum is used in anatomy to designate a lip edge or brim. The glenoid labrum glenoid ligament is a fibrocartilaginous structure not a fibrocartilage as previously thought rim attached around the margin of the glenoid cavity in the shoulder blade.

In anatomy and physiology the term labrum is used to refer to an edge or a brim. Deepening the joint and increasing the surface area of the hip socket by 21 1. Anatomy of the shoulder featuring the humerus upper arm bone and the labrum.

Blood supply and innervation. The fibrocartilage is is arranged in three distinct layers. In medicine a ring of fibrocartilage fibrous cartilage around the edge of the articular joint surface of a bone.
