5 Matching questions

  1. What are the parasympathetic ganglions in the face?
  2. Explain the function of the pterygopalatine ganglion.
  3. What are the divisions of the pharynx.
  4. Explain how taste occurs.
  5. What is the role of the geniculate ganglion?
  1. a Behind maxiallary sinus. Postganglionic sympathics from greater petrosal nerve (facial) for parasympth. of nasal/lacramal/palatine glands. also branches of the trigeminal
  2. b It is the sensory ganglion for taste from the facial nerve (through the lingual nerve).
  3. c COPS:
    Ciliary (III), Otic (IX), Pterygopalatine (VII), Submandibular (VII).
  4. d 1. Nasopharynx
    2. Oropharynx
    3. Laryngopharynx
  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. 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. 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.
  3. 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.
  4. Falx Cerebri: divides the cerebral lobes
    Tentorium Cerebelli: Divides the cerebrum from the pons- except for the tentorial notch w/ allows communication
  5. Has a cranial and spinal root. Spinal root comes to join the cranial root in the skull and then they leave the skull. Cranial root becomes apart of the vagus nerve and the spinal root innervates the traps and sternocleidomastoid. PAIN GOES TO CERVICAL NOT CRANIAL ROOTS.

5 True/False questions

  1. What are the components of the gag reflex?1. Nasopharynx
    2. Oropharynx
    3. Laryngopharynx

          

  2. Explain the pathway of the facial nerve (CNVII)Supplies muscle of the tongue. Especially the genioglossus muscle going from the tip of the mandible to the posterior portion of the tongue.

          

  3. Explain the function of the hypoglossal nerve (CNXII)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.

          

  4. What is the difference between the optic nerve and the optic track? How does crossing work in the nerves of the optic nerve.Falx Cerebri: divides the cerebral lobes
    Tentorium Cerebelli: Divides the cerebrum from the pons- except for the tentorial notch w/ allows communication

          

  5. What muscles responsible for looking up and down?Opening- Levator palpebrae superioris
    Closing- orbicularis oculi
