Labrum anatomy. The glenoid labrum is approximately 4 mm thick and is round or triangular in cross section. Glenoid labrum gross anatomy. The term labrum is used in anatomy to designate a lip edge or brim.
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 acetabular labrum is a ring of cartilage that surrounds the acetabulum of the hip. 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.
The anterior portion is most vulnerable when the labrum tears. One arm of the biceps tendon long head also attaches to the shoulder labrum at its top. The outer glenoid is vascular and the inner glenoid is avascular 4.
A labral tear occurs when the cartilage is torn. The labrum is a thick fibrous ring that surrounds the glenoid. The shoulder joint is considered a ball and socket joint.
The fibrocartilage is is arranged in three distinct layers. Deepening the joint and increasing the surface area of the hip socket by 21 1. It is a fibro cartilaginous rubbery structure which encircles the glenoid cavity deepening the socket providing static stability to the glenohumeral joint.
It is triangular in cross section. The glenoid labrum is similar to the meniscus of the knee. The labrum surrounding the shoulder socket is called the the glenoid labrum.
Anatomy of the shoulder featuring the humerus upper arm bone and the labrum. In anatomy and physiology the term labrum is used to refer to an edge or a brim. Allowing for a significant range of motion.
Blood supply and innervation. Keeping joint fluid inside the hip joint capsule joint fluid. The labrum is thickest posterosuperiorly and widest anterosuperiorly.
The labrum serves several purposes including. It coats the surface of the socket area with a soft cartilage enabling the shoulder to move more freely and painlessly. Circumferentially orientated layer with radial reinforcing filaments.
In medicine a ring of fibrocartilage fibrous cartilage around the edge of the articular joint surface of a bone. It provides an articulating surface for the acetabulum allowing the head of the femur to articulate with the pelvis. The term labrum is used in anatomy to designate a lip edge or brim.
