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.AnatomyMorphology and Connection PointsThe teres minor originates from the dorsal surface of the lateral border of the scapula. This origin generally receives support from two aponeurotic septa located between

Subscapularis Muscle is a deep muscle that plays a critical role in shoulder mobility and stability. As the largest and strongest member of the rotator cuff, it performs essential functions in both daily activities and athletic movements. This text provides a detailed examination of the subscapularis muscle’s anatomical structure, morphological features, embryological origin, innervation and vascular supply, and its clinical significance.Anatomical StructureMorphology and Attachment PointsThe su

The Supraspinatus Muscle originates from the supraspinous fossa at the top of the scapula (shoulder blade) and extends to the greater tubercle of the humerus. It is one of the four muscles of the rotator cuff and plays a critical role in initiating abduction (raising) of the arm from the shoulder.AnatomyMorphology and Connection PointsThe Supraspinatus Muscle originates from the medial two-thirds of the supraspinous fossa of the scapula. After passing over the spine of the scapula, its fibers in

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.AnatomyMorphology and Connection PointsThe Infraspinatus Muscle originates from the medial two-thirds of the infraspinous fossa of the scapula and the overlying infraspinatus fascia.
