Name a muscle located at the temples of the head.

The temporalis muscle is indeed the correct answer as it is specifically located at the temples of the head. This fan-shaped muscle plays a crucial role in the function of the jaw, as it is primarily responsible for elevating and retracting the mandible, contributing to the action of chewing. Its position at the temples makes it recognizable, as it covers a significant area on the side of the skull and extends down to attach to the mandible.

The sternocleidomastoid is located in the neck and is responsible for head rotation and flexion. The masseter is a key muscle of mastication situated at the jaw, playing a major role in chewing but not at the temporal region. The zygomaticus major, while involved in facial expressions such as smiling, is located in the cheek area and does not pertain to the temples of the head. Understanding the specific locations and functions of these muscles provides a better grasp of their roles in anatomy and movement.
