Rotator cuff muscles and deltoid muscle

The video tutorial provides an in-depth look at the rotator cuff and deltoid muscles, focusing on their anatomy, functions, and innervations. It covers the four rotator cuff muscles, known as the SITS muscles, and their roles in shoulder movement and stabilization. The tutorial also explains the deltoid muscle's structure and its contribution to shoulder movements. Innervation details are provided, highlighting the involvement of the brachial plexus and specific nerves.
