The brachialis muscle is one of the three muscles of the anterior compartment of the upper arm.Unlike biceps brachii (which is also a supinator) it acts only to flex the elbow. Isolated brachialis injuries are rare. Summary. Brachialis has a large superficial head and a smaller deep head. The superficial head origin is the anterolateral mid humeral shaft and lateral intermuscular septum. The Brachioradialis (Supinator longus) is the most superficial muscle on the radial side of the forearm. It arises from the upper two-thirds of the lateral supracondylar ridge of the humerus, and from the lateral intermuscular septum, being limited above by the groove for the radial nerve. Interposed between it and the Brachialis are the radial The brachialis has no attachment to the radius, so it is not involved in pronation and supination. Because of its superficial location and greater volume, the superficial head of the brachialis is mechanically more suitable to stabilize the arm in flexion. It is at its strongest at a 90-degree flexion of the arm. The Brachialis ( Brachialis anticus) covers the front of the elbow-joint and the lower half of the humerus. It arises from the lower half of the front of the humerus, commencing above at the insertion of the Deltoideus, which it embraces by two angular processes. Its origin extends below to within 2.5 cm. of the margin of the articular surface. Attachments of Brachialis Muscle: Origin & Insertion. Origin: (proximal attachments): Anterior, distal half of humerus. Insertion: (distal attachments): Coronoid process and tuberosity of ulna.
