What is the insertion point of the teres minor muscle?

The teres minor muscle has its insertion point at the greater tubercle of the humerus. This muscle is part of the rotator cuff and plays a crucial role in the lateral rotation of the arm and stabilization of the shoulder joint.

The greater tubercle is a prominent bony landmark on the humerus where several important shoulder muscles attach. Specifically, the teres minor, along with the supraspinatus and infraspinatus, contributes to the overall function of the shoulder in terms of mobility and stability. Knowing the correct attachment points is essential for understanding how the muscles work in tandem during various movements and activities.

The other options do not reference locations associated with the teres minor muscle's anatomical structure or its function within the shoulder. The lesser tubercle of the humerus, for instance, serves as the attachment point for the subscapularis muscle, while the lateral olecranon process pertains to the ulna in the forearm, and the lateral shaft of the radius is related to the radius bone rather than shoulder muscles. Recognizing specific muscle insertions helps in diagnosing problems and providing effective treatment during sports massage or rehabilitation.
