“glenoid labrum” definition:

The glenoid labrum is a part of the human shoulder joint. It is a ring of cartilage in the shape of a shallow dish that surrounds and attaches to the back of the head of the humerus.

The glenoid labrum is a fibrocartilaginous structure that wraps partially around the glenoid cavity and attaches to the margin of the acetabulum. It provides stability and depth to the joint.

The labrum is made up of three layers: an outer fibrous layer, an inner vascularized cartilage layer, and an intermediate layer with both fibrous and cartilage. The labrum can be divided into two parts - a deep part that attaches to the rim of the iliac crest, and a superficial part that attaches to the rim of the acetabulum.
