The subclavius muscle originates from the costal cartilage of the first rib and inserts in the clavicle near the acromion. It is innervated by the subclavian nerve, which branches from the brachial plexus. The subclavius muscle is supplied by the thorocoacromion artery. This muscle helps stabilize the clavicle and elevate the first rib. Research Subclavius
