Which structure does the teres minor muscle attach to distally?

The teres minor muscle attaches distally to the greater tubercle of the humerus. This attachment point is significant as it allows the teres minor to play a crucial role in shoulder movement, particularly during external rotation and stabilization of the humeral head within the glenoid cavity. The greater tubercle serves as a site for rotator cuff muscles, which contribute to the overall function and stability of the shoulder joint. Understanding the relationship between the teres minor and the greater tubercle is essential for grasping the mechanics of shoulder movements and the role of various muscles in facilitating those motions.
