    Below are written questions from previous quizzes and exams. Click here for a Practical Quiz - old format or Practical Quiz - new format.

  1. A sixty-four-year old man was diagnosed with an acoustic neuroma (tumor of the VIIIth cranial nerve) where it entered the temporal bone. What other cranial nerve might also be affected since this nerve uses the same foramen as the VIIIth in its course?
    Abducens
    Facial
    Glossopharyngeal
    Trigeminal
    Vagus
  2. Infections may spread from the nasal cavity to the meninges along the olfactory nerves, as its fibers pass from the mucosa of the nasal cavity to the olfactory bulb via the:
    Cribriform plate of the ethmoid
    Crista galli
    Foramen caecum
    Superior orbital fissure
  3. A patient who has sustained a fracture to the middle cranial fossa following a fall from a height, might have any of these nerves injured EXCEPT:
    Trigeminal
    Oculomotor
    Abducens
    Trochlear
    Hypoglossal
  4. The glossopharyngeal nerve exits the skull via what opening?
    Foramen ovale
    Carotid canal
    Jugular foramen
    Hypoglossal canal
    Stylomastoid foramen
  5. All of the following nerves exit the cranial cavity by way of bony openings located in the middle cranial fossa EXCEPT:
    Abducens
    Trochlear
    Oculomotor
    Trigeminal
    Facial
  6. An infant was diagnosed as having hydrocephalus. It was determined that there was a blockage in the ventricular system of the baby's brain between the third and fourth ventricles. The blockage therefore must have involved the:
    Central canal
    Cerebral aqueduct
    Foramen of Luschka (lateral foramen)
    Foramen of Magendie (medial foramen)
    Interventricular foramen
