| fossa | Hollow, grooved, or depressed area in a bone |
| frontal | region of the head pertaining to the forehead |
| frontal process | process of the zygomatic bone that extends upward to articulate with the frontal bone at the outer edge of the orbit |
| glenoid fossa | Area of the temporal bone where condyles of the mandible articulate with the skull |
| greater palatine | nerve that serves the posterior hard palate and the posterior lingual gingiva |
| hamulus | a hook shaped process |
| infraorbital | Region of the head below the orbital region |
| lacrimal bones | paired facial bones that help form the medial wall of the orbit |

| symphysis menti | The separation of the mandible at the chin that occurs at birth |
| temporal | Region of the head superior to the zygomatic arch |
| temporal process | Process that articulates with the zygomatic process of the temporal bone to form the zygomatic arch, which creates the prominence of the cheek. |
| temporomandibular joint | joint on each side of head that allows movement of the mandible |
| trapezius | Major cervical muscle |
| trigeminal nerve | The nerve that is the primary source of innervation for the oral cavity. |
| zygomatic | Region of the head pertaining to or located near the zygomatic bone (cheekbone). |
