What is the function of the labrum in the glenohumeral?

The labrum in the glenohumeral joint, commonly known as the shoulder joint, serves as a fibrocartilaginous structure that deepens the glenoid cavity, providing increased stability and support to the joint. It helps to anchor the head of the humerus, enhancing the fit between the ball-and-socket components of the joint. Additionally, the labrum acts as an attachment point for ligaments and tendons, contributing to the overall function and stability of the shoulder.
