  2. What is the role of the geniculate ganglion?
  3. What is the difference between the optic nerve and the optic track? How does crossing work in the nerves of the optic nerve.
  4. Explain the flow of veins in the brain.
  5. What are the parasympathetic ganglions in the face?
  1. a 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.
  2. b Optic Nerve: eye to chiasm
    Optic Tract: chiasm to brain
    Nasal portion nerves cross in chiasm while the lateral portions do not. Thus left field processed by right side of the brain and vice-versa.
  3. c Opening- Levator palpebrae superioris
    Closing- orbicularis oculi
  4. d COPS:
    Ciliary (III), Otic (IX), Pterygopalatine (VII), Submandibular (VII).
  5. e It is the sensory ganglion for taste from the facial nerve (through the lingual nerve).

5 Multiple choice questions

  1. Up- Superior oblique and inferior rectus
    Down- Inferior oblique and superior rectus
  2. 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.
  3. Adduction: Medial, Superior, Inferior rectus
    Abduction: Lateral, superior, inferior obliques

  1. Explain the structures in the cavernous sinus.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.

          

  2. What is the role of the otic ganglion?glossopharngeal (CNIX) sends preganglionic parasymphatetics to the parotid gland.

          

  3. Explain the peripheral pathway of the CNI- Olfactory nerve.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. What are the divisions of the pharynx.1. Nasopharynx
    2. Oropharynx
    3. Laryngopharynx

          

  5. Explain the jugular foramen?Where the jugular vein leaves as well as CN 9, 10, 11. (Vagus, glosspharngeal, accessory).
