The brachialis muscle is the main flexor of the forearm. It arises from the distal, anterior half of the humerus and the intermuscular septa. It inserts into the coronoid process and tuberosity of the ulna over the elbow joint.

The innervation of brachialis is:

  • musculocutaneous nerve; main supply and predominantly C6
  • radial nerve; C7 root supplies branches to the lateral part of brachialis
