Superficial blood vessels of the head

This video tutorial explores the anatomy and function of shoulder muscles, focusing on the rotator cuff, which includes the supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles stabilize the humeral head in the glenoid cavity and facilitate arm rotation. Additional muscles like the deltoids, coracobrachialis, and pectoralis major and minor also contribute to shoulder movement. The video concludes with a call to explore more resources on Kenhub.
