- a Up- Superior oblique and inferior rectus
Down- Inferior oblique and superior rectus
- b 1. Nasopharynx

5 True/False questions
What are the components of the gag reflex? → 1. Cervical
Explain the jugular foramen? → Anterior 2/3 is the facial nerve (CNVII) through lingual nerve.
Posterior 1/3 is the glossopharngeal nerve (CN IX)
What are the branches of the facial nerve? → 1. Cervical
Explain the specific branches of the mandibular nerve. → 1. Cervical
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.
