Hypoglossal canal: occipital condyles, mastoid process, styloid process, mandibular (glenoid) fossa & articular tubercle, unites cranial and facial bones. Roof of nasal cavity: medial wall of the orbits (cid:862)keystone of skull(cid:863) Nerve: cn v trigeminal nerve (cn v3) Nerve: all innervated by cn iii oculomotor (except. Attach to hyoid and mandible or temporal bone: mandible fixed = elevates hyoid (swallowing) Attach to hyoid, thyroid cartilage (larynx) and sternum. Inferior and anterior parts of the frontal lobes occupy this space. Greater part of the fossa is formed by the orbital parts of the frontal bone supports the front lobe of the brain and forms the roofs of orbits: middle cranial fossa. Posteo-inferior to the anterior cranial fossa: posterior cranial fossa. Largest and deepest of the three cranial fossae. The orbits are bilateral bony cavities in the. Lateral walls are ~ 90o angle facial skeleton surfaces parallel. Contains: base, four walls and apex: base of orbit.
