What is the origin of the temporalis muscle?

The temporalis muscle originates from the temporal bone, which is a key structure in the skull located on the sides and base of the cranium. This muscle plays a significant role in the process of mastication (chewing) by elevating and retracting the mandible (lower jaw). The fibers of the temporalis muscle spread out from the temporal fossa of the temporal bone and converge into a strong tendon that attaches to the coronoid process of the mandible.

Understanding the exact origin of muscles is crucial for students in the field of mortuary science as it provides insights into human anatomy, relevant for restorative art and other practical applications in preparing deceased individuals.
