Dissection of left temporal region
Temporal muscle, lateral view
The zygomatic arch has been resected to reveal a separate layer of muscle (8) which arises from the inner surface of the arch and inserts on the coronoid process of the mandible. This muscle fascicle is supplied by a branch of masseteric nerve (12). A delicate sheet of muscle fibres related to the temporal fascia covers the main mass of the temporal muscle and is supplied by a branch (6) of the anterior deep temporal nerve.
