The sternocleidomastoid muscle is responsible for turning the head down and to the left and right. It is a long muscle located on either side of the neck and is used in everyday movements such as looking over the shoulder while driving or turning to acknowledge someone in conversation. The other muscles listed (Frontalis, Pectoralis major, Diaphragm) are not involved in the movement of turning the head in this way.
