- What divides the anterior, medial, and posterior cranial fossa?
- Explain the peripheral pathway of the CNVII- oculomotor nerve.
- a Has voluntary movement and parasymphthetic constriction of the eye. As such- synapse in the ciliary ganglion behind the eye and the to the brain. REMEMBER THIS SYNAPSE before going to the brain.
- b Sensory- glossopharngeal

- Enters the internal acoustic meatus to hit the geniculate ganglion. Main branch goes out the stylomastoid foramen to supply face muscles, while it sends a chorda tympani branch to join lingual to go to submandibular/mental glands and carry taste. A smaller branch leaves geniculate ganglion called the greater petrosal nerve to hit the pterygopalatine ganglion and supply other glands.
- Supplies muscle of the tongue. Especially the genioglossus muscle going from the tip of the mandible to the posterior portion of the tongue.
5 True/False questions
Where is the hypogloassal canal? → On the side of the foramen magnum
What are the different duramatter in the brain? → 1. Nasopharynx
Explain the specific branches of the mandibular nerve. → 1. Cervical
Explain the function of the submandibular ganglion. → Chorda typani (facial) post ganglionic parasympathtics to the submandibular gland and the submental gland.
Explain the peripheral pathway of the CNVIII- Vestibulocochlear nerve. → 1. Cochlear (for hearing) in the spiral part of the middle ear goes to the spiral ganglion (cell bodies)
2. Vestibular (balance) in the vestibular appartus goes to the vestibular ganglion (cell bodies)
Axons from both of these converge to leave middle ear to the brain.
