Anterior Arm Compartment - Biceps Brachii, Brachialis, & Coracobrachialis

The video tutorial provides an in-depth look at the major muscles of the anterior compartment of the arm, focusing on the biceps brachii, coracobrachialis, and brachialis. It explains their anatomical positions, origins, insertions, functions, and innervations. The biceps brachii is highlighted for its role in elbow flexion and forearm supination, while the coracobrachialis assists in shoulder adduction and flexion. The brachialis is emphasized as the primary muscle for elbow flexion, regardless of forearm position.
