The Teres Minor Muscle is a narrow, long muscle of the rotator cuff. It originates from the lateral border of the scapula and inserts onto the greater tubercle of the humerus. It plays a critical role in stabilizing the shoulder joint and helps center the humeral head in the glenoid cavity. Anatomy Morphology and Connection Points The teres minor originates from the dorsal surface of the lateral border of the scapula. This origin generally receives support from two aponeurotic septa located betw

The Infraspinatus Muscle is a thick, triangular-shaped muscle that occupies most of the infraspinous fossa located on the posterior surface of the scapula. It serves as one of the four muscles of the rotator cuff, and its primary functions are external rotation of the humerus and stabilization of the shoulder joint. Anatomy Morphology and Connection Points The Infraspinatus Muscle originates from the medial two-thirds of the infraspinous fossa of the scapula and the overlying infraspinatus fasci
