The glenoid labrum is continuous with which structures?

The glenoid labrum is an important fibrocartilaginous structure that provides stability to the shoulder joint by deepening the glenoid cavity. It is indeed continuous with several structures that contribute to the overall function and stability of the shoulder.

The deltoid muscle, while not directly attached to the labrum, is nearby and plays a crucial role in shoulder movement. The continuity in muscle function and proximity is essential for the shoulder's overall biomechanics.

The long head of the biceps tendon is anchored to the superior portion of the glenoid labrum. This anatomical connection plays a significant role in shoulder stability and function, as the biceps help with flexing the elbow and lifting the arm. The integration of the biceps tendon with the labrum ensures proper transmission of forces and stability during shoulder motions.

The glenohumeral ligaments (superior, middle, and inferior) also blend with the glenoid labrum, reinforcing the shoulder joint and adding to its stability. These ligaments help prevent excessive movement of the humeral head within the glenoid cavity, especially in various arm positions.

Considering these relationships, stating that the glenoid labrum is continuous with all of these structures is accurate. Each plays a vital role in maintaining shoulder
