  1. Explain the internal acoustic meatus?
  2. What is the structure of duramatter.
  3. Explain the peripheral pathway of the CNI- Olfactory nerve.
  4. What are the different duramatter in the brain?
  5. Explain the peripheral pathway of the CNVII- oculomotor nerve.
  1. 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.
  2. b Falx Cerebri: divides the cerebral lobes
    Tentorium Cerebelli: Divides the cerebrum from the pons- except for the tentorial notch w/ allows communication
  3. c 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. d CN 7 and CN 8 (Facial and vestibulacoclear) leave the skull.
  5. e Two layers:
    1. meningeal layer (to tissue)
    2. periosteal layer (to the skull)
    The area in between the two is sinus where vein can travel.

  2. What are the parasympathetic ganglions in the face?glossopharngeal (CNIX) sends preganglionic parasymphatetics to the parotid gland.


  3. What is the role of the geniculate ganglion?It is the sensory ganglion for taste from the facial nerve (through the lingual nerve).


  4. Explain the flow of veins in the brain.Down posterior through superior saggital sinus of the falx cerebri. then through the transverse sinus of the tentorium cerebelli. then to the internal jugular vein.


  5. What divides the anterior, medial, and posterior cranial fossa?glossopharngeal (CNIX) sends preganglionic parasymphatetics to the parotid gland.
