Muscles of the arm and shoulder

This tutorial explores the muscles of the arm and shoulder, focusing on their anatomy and attachment points. It covers the anterior and posterior arm muscles, including the biceps brachii, brachialis, and triceps brachii, as well as the shoulder muscles like the deltoid and the rotator cuff group. The video also discusses common rotator cuff injuries and prevention strategies. A mnemonic is provided to help remember the rotator cuff muscles.
