Shoulder joint

This tutorial explores the shoulder joint from a lateral view, focusing on its anatomy, including bones, ligaments, muscles, and bursae. It covers the glenohumeral joint's structure, highlighting the humerus and scapula, and discusses the joint cavity, ligaments, and muscles like the rotator cuff. The tutorial also addresses bursae and clinical conditions such as subacromial bursitis, providing a comprehensive understanding of the shoulder joint's anatomy and function.
