Where does the temporalis muscle insert?

The temporalis muscle is a crucial muscle involved in the mastication process, specifically in the elevation and retraction of the mandible. It originates from the temporal fossa of the temporal bone and the fascia covering the temporalis muscle. The correct insertion point is the coronoid process of the mandible.

The coronoid process is a flat, triangular projection of the mandible where the temporalis muscle attaches. This anatomical positioning allows the muscle to effectively exert force when chewing and helps in the overall movement of the jaw while eating or speaking.

Understanding the function and insertion of the temporalis muscle is essential for those studying anatomy, particularly in fields related to dentistry, orthodontics, and mortuary science, as it provides insight into the biomechanics of the jaw and temporomandibular joint.
