Which is an insertion of the temporalis?

Coronoid process of the mandible Condylar process of the mandible Angle of the mandible External oblique surface of the mandible

Correct Answer:

Coronoid process of the mandible

Explanation:

The key idea is where the temporalis muscle attaches to the mandible. The temporalis has a broad origin from the temporal fossa and travels to insert on the coronoid process of the mandible. This insertion lets the muscle elevate the mandible, and its fibers along the coronoid region contribute to bringing the jaw upward and, with some fibers, retracting it. The condylar process is part of the jaw that participates in the temporomandibular joint, not the insertion point for temporalis. The angle of the mandible and the external oblique line are attachment sites more closely associated with other muscles, such as the masseter, rather than temporalis.
