Final answer:
The temporal process of the Zygoma and the Zygomatic process of the temporal bone come together to form the zygomatic arch, an important structure for muscle attachment on the side of the skull.
Step-by-step explanation:
The zygomatic arch is a distinct bony arch on the side of the skull, playing a vital role in facial structure and muscle attachment. It is constructed from two connecting bony processes: the temporal process of the zygomatic bone, which extends posteriorly, and the zygomatic process of the temporal bone, which extends anteriorly.
Together, they form an elongated, free-standing arch that spans from the cheek region to above the ear canal. This arch is critical for various functions, including the attachment of facial muscles involved in mastication, as the major muscles that elevate the mandible during biting and chewing originate from the zygomatic arch. The intricate design of these bone structures highlights their significance in the anatomy of the skull, where the temporal process and zygomatic process interlock much like the closing of a drawbridge, creating the zygomatic arch. The zygomatic bone, also known as the cheekbone, contributes to this arch and aids in forming the lateral wall of the orbit and the lateral-inferior margins of the anterior orbital opening.
