Since the nerves of the brachial plexus pass through the space between the anterior and middle scalene muscles, that area is sometimes targeted with the administration of regional anesthesia by physicians. The nerve block, called an interscalene block, may be performed prior to arm or shoulder surgery.he action of the anterior and middle scalene muscles is to elevate the first rib and laterally flex (bend) the neck to the same side; the action of the posterior scalene is to elevate the second rib and tilt the neck to the same side.
They generally attach to the sides of the neck vertebrae at the top and to the uppermost ribs at the bottom. So the scalenes are mostly head pullers: they pull the head from side to side. And although they certainly do move the neck, they are also breathing muscles, because of the way they pull up on the ribs.ust like the pain of a heart attack spreads from the heart into the shoulder and arm, the pain of painful scalene muscles spreads throughout the chest, upper back, and chest, the arm and hand, and the side of the head. Pain referred to the back may feel like a penetrating pain stabbing through the torso.
