5 Written questions

5 Matching questions

  1. Explain where the trigeminal nerve exits externally.
  2. Explain the specific branches of the mandibular nerve.
  3. What are the branches of the facial nerve?
  4. Explain the flow of veins in the brain.
  5. Explain the internal acoustic meatus?
  1. a CN 7 and CN 8 (Facial and vestibulacoclear) leave the skull.
  2. b 1. Supraorbital notch
    2. Infraorbital foramen
    3. Mental foramen
  3. c 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. d 1. Cervical
    2. Buccal
    3. Zygomatic
    4. Mandibular
    5. temporal
  5. e Has the lingual (sensation to tonuge) and the mental (sensation to mandible) components.

5 Multiple choice questions

  1. Adduction: Medial, Superior, Inferior rectus
    Abduction: Lateral, superior, inferior obliques
  2. 1. cribiform plate with holes for the olfactory nerve
    2. Carotid canal, foramen ovale
    3. Magnum foramen, internal accousti meatus, jugular foramen
  3. 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. 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.
  5. Sensory- glossopharngeal
    Motor- vagus

5 True/False questions

  1. 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

          

  2. What muscles responsible for extortion and intorsion of the eye?Adduction: Medial, Superior, Inferior rectus
    Abduction: Lateral, superior, inferior obliques

          

  3. Explain the peripheral pathway of the CNVII- oculomotor 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 functions of the trigeminal nerve (CNV)Supplies muscle of the tongue. Especially the genioglossus muscle going from the tip of the mandible to the posterior portion of the tongue.

          

  5. What muscles are responsible for opening and closing the eye?Extorsion: Inferior oblique and rectus
    Intorsion: Superior oblique and rectus
