This tutorial covers the anatomy and function of the brachial muscles, including the biceps brachii, coracobrachialis, brachialis, and triceps brachii. It explains the actions and innervations of these muscles, focusing on their roles in elbow flexion and extension. The biceps brachii is highlighted for its role in supination, while the triceps brachii is noted for elbow extension. The tutorial also discusses the musculocutaneous and radial nerves, emphasizing their pathways and potential risks in case of fractures.
