Rotator Cuff Muscles | Origins, Insertions, Innervations, and Actions

The video tutorial provides an in-depth look at the rotator cuff muscles, distinguishing them from the shoulder girdle muscles. It covers the anatomy of the scapula and humerus, focusing on the four rotator cuff muscles: supraspinatus, infraspinatus, teres minor, and subscapularis. Each muscle's origin, insertion, blood supply, innervation, and function are discussed, with emphasis on their roles in shoulder movement and stability. The video also explains why teres major is not considered a rotator cuff muscle.
