Temporal Muscle Laterally

The temporal muscle, also known as the temporalis, is one of the muscles of mastication. It covers much of the temporal bone. It arises from the temporal fossa and the deep part of temporal fascia. It passes medial to the zygomatic arch and inserts onto the coronoid process of the mandible. The temporal muscle is covered by the temporal fascia, also known as the temporal aponeurosis. The muscle is accessible on the temples, and can be seen and felt contracting while the jaw is clenching and unclenching.
