Where is the temporalis muscle located?

Where is the temporalis muscle located explain its function?

Where is the masseter and temporalis muscle located?
The masseter muscle provides powerful elevation and protrusion of the mandible by originating from the zygomatic arch and inserting along the angle and lateral surface of the mandible. The temporalis muscle originates from the floor of the temporal fossa and inserts onto the coronoid process of the mandible.
What is the purpose of temporalis muscle?
The temporalis muscle runs superficially, from the temporal bone to the coronoid process of mandible. The main function of this muscle is to produce the movements of the mandible at the temporomandibular joint and thus facilitate the act of mastication.

Which of the following is typically an insertion of the temporalis muscle?

| Origin | Temporal fossa (up to inferior temporal line), Temporal fascia |
|---|---|

| Action | Anterior fibres: Elevates mandible Posterior part: Retracts mandible |
| Innervation | Deep temporal branches (of mandibular nerve (CN V3)) |
What do bipedalism’s advantages over Quadrupedalism include?
