The temporal fossa is a shallow depression on the side of the skull, located above the zygomatic arch and below the temporal line. It serves as an important area for the attachment of the temporalis muscle, which is involved in chewing. The fossa is bordered by several bones, including the frontal, parietal, temporal, and sphenoid bones. This anatomical feature plays a crucial role in the structure of the skull and the function of the jaw. The temporalis muscle originates from the temporal fossa and helps elevate the mandible during mastication. Understanding the temporal fossa is essential for studying craniofacial anatomy and related medical fields.
