Final answer:
The jaw joint part located on the zygomatic arch is formed by the union of the temporal process of the zygomatic bone and the zygomatic process of the temporal bone.
Step-by-step explanation:
Part of the Jaw Joint on the Zygomatic Arch:
The name of the part of the jaw joint located on the zygomatic arch, which spans from the cheek area to just above the ear canal, is formed by the union of two particular processes. These are the temporal process of the zygomatic bone (anteriorly), also known as the cheekbone, and the zygomatic process of the temporal bone (posteriorly). Together, these form the zygomatic arch, as seen from a lateral view of the skull. Moreover, one of the major muscles that elevate the mandible during biting and chewing originates from this very zygomatic arch.
