  1. What are the structures of the:
    1. anterior base of the skull
    2. medial base of the skull
    3. posterior base of the skull
  2. What is the role of the otic ganglion?
  3. What are the functions of the trigeminal nerve (CNV)
  4. What muscles responsible for adduction and abduction of the eye?
  5. Explain how taste occurs.
  1. a glossopharngeal (CNIX) sends preganglionic parasymphatetics to the parotid gland.
  2. b Adduction: Medial, Superior, Inferior rectus
    Abduction: Lateral, superior, inferior obliques
  3. c Sensory/motor
    Opthalmic- sensation to forehead and cornea
    Maxillary- sensation to maxillary and upper teeth
    Mandibular- sensation to madible and works chewing muscles
  4. d 1. cribiform plate with holes for the olfactory nerve
    2. Carotid canal, foramen ovale
    3. Magnum foramen, internal accousti meatus, jugular foramen
  5. e Anterior 2/3 is the facial nerve (CNVII) through lingual nerve.
    Posterior 1/3 is the glossopharngeal nerve (CN IX)

5 Multiple choice questions

  1. Supplies muscle of the tongue. Especially the genioglossus muscle going from the tip of the mandible to the posterior portion of the tongue.
  2. Opening- Levator palpebrae superioris
    Closing- orbicularis oculi
  3. Receptors in the nose travel to the cell bodies in the olfactory bulb that sits on the cribiform plate of the ethmoid bone. Here axons continue to the brain.
  4. CN 7 and CN 8 (Facial and vestibulacoclear) leave the skull.
  5. Where the jugular vein leaves as well as CN 9, 10, 11. (Vagus, glosspharngeal, accessory).

5 True/False questions

  1. Explain the function of the pterygopalatine ganglion.Chorda typani (facial) post ganglionic parasympathtics to the submandibular gland and the submental gland.


  2. What are the branches of the facial nerve?Sensory- glossopharngeal
    Motor- vagus


  3. What muscles responsible for looking up and down?Up- Superior oblique and inferior rectus
    Down- Inferior oblique and superior rectus


  4. Explain branching of the internal carotid artery.Splits into:
    1. opthalmic (eye supply)
    2. Middle cerebral (lateral side of brain)
    3. Anterior cerebral (anterior medial portion of the brain)
    Anastomoses with the vertebral artery.


  5. 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.
