Brachialis
The brachialis muscle is located in the upper arm.
It lies underneath the biceps muscle. It acts as a structural bridge between the humerus, which is the bone of the upper arm, and the ulna, which is one of the forearm bones.
The muscle is innervated by both the musculoskeletal nerve and the radial nerve.
In some people, the muscle may appear doubled. Also called the brachialis anticus, its primary action is to flex the forearm muscles at the elbow.
