5 Written questions

5 Matching questions

  1. What are the divisions of the pharynx.
  2. What muscles are responsible for opening and closing the eye?
  3. Explain the pathway of the facial nerve (CNVII)
  4. Explain the function of the submandibular ganglion.
  5. Explain the jugular foramen?
  1. a Where the jugular vein leaves as well as CN 9, 10, 11. (Vagus, glosspharngeal, accessory).
  2. b 1. Nasopharynx
    2. Oropharynx
    3. Laryngopharynx
  3. c Opening- Levator palpebrae superioris
    Closing- orbicularis oculi
  4. d 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.
  5. e Chorda typani (facial) post ganglionic parasympathtics to the submandibular gland and the submental gland.

5 Multiple choice questions

  1. Falx Cerebri: divides the cerebral lobes
    Tentorium Cerebelli: Divides the cerebrum from the pons- except for the tentorial notch w/ allows communication
  2. Anterior 2/3 is the facial nerve (CNVII) through lingual nerve.
    Posterior 1/3 is the glossopharngeal nerve (CN IX)
  3. 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.
  4. 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.
  5. Up- Superior oblique and inferior rectus
    Down- Inferior oblique and superior rectus

5 True/False questions

  1. What muscles responsible for adduction and abduction of the eye?Adduction: Medial, Superior, Inferior rectus
    Abduction: Lateral, superior, inferior obliques

          

  2. Explain the function of the hypoglossal nerve (CNXII)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 where the trigeminal nerve exits externally.1. Supraorbital notch
    2. Infraorbital foramen
    3. Mental foramen

          

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