KINE 3135: The Shoulder Joint

The video tutorial covers the anatomy and movements of the shoulder joint, emphasizing the importance of understanding basic concepts over memorizing details. It distinguishes between shoulder girdle and joint movements, explains the anatomy of the shoulder joint, and identifies key muscles involved. The tutorial also discusses various shoulder joint movements, such as flexion, extension, abduction, and adduction, and highlights the roles of agonist and antagonist muscles in these movements.
