Shoulder Anatomy and Muscles

The video tutorial provides a comprehensive overview of the anatomy of the scapula, clavicle, and humerus. It begins with a detailed description of the scapula, highlighting its borders, angles, and bony projections. The tutorial then covers the muscles of the rotator cuff and other muscles attached to the scapula. It explains how to identify the right scapula using anatomical features. The anatomy of the clavicle is discussed, focusing on its articulations with the sternum and acromion process. Finally, the video explores the humerus, emphasizing its proximal end, surgical neck, and clinical significance.
