The anterior compartment of the arm is known as the "flexor compartment" as flexion is its main action.
The muscles contained therein are the biceps brachii, brachialis, and coracobrachialis.
They are all supplied by the musculocutaneous nerve, which arises from the fifth, sixth, and seventh cervical spinal nerves ("see Brachial plexus").
