front 37 A bridgelike projection joining the zygomatic bone (cheekbone) anteriorly. Together these two bones form the zygomatic arch. | back 37 Zygomatic Process |
front 38 Rounded depression on the inferior surface of the zygomatic process; forms the socket for the mandibular condyle, the point where the mandible joins the cranium. | back 38 mandibular fossa |
front 39 External Acoustic Meatus | back 39 canal leading to ear drum and middle ear |
front 40 Needle like projection inferirior to external acoustic meatus; attachment point for muscles and ligaments of the neck. This process is often broken off demonstration skulls. | back 40 Styloid Process |
