  1. During an intramural baseball game a player is hit in the side of the head, between the eye and the ear. He immediately loses consciousness, wakes up momentarily and then becomes comatose. He is rushed to the ER and is immediately given a CT scan. The scan shows a skull fracture and an accumulation of blood between the dura and the cranial bone on the side of his head, compressing his cerebrum. He is rushed to surgery where a hole is bored into his skull to relieve the pressure. After a few tense hours, he regains consciousness and has an uneventful recovery. The hemorrhage from the fracture would be described as:
    Epidural
    Intracerebral
    Subaponeurotic
    Subarachnoid
    Subdural
  2. 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
  3. 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
  4. The "danger zone" of the scalp is recognized as which of the following layers?
    Galea aponeurotica
    Loose connective tissue
    Pericranium
    Skin
    Subcutaneous connective tissue
  5. An infection in which scalp layer is likely to spread most readily?
    Skin
    Connective tissue layer
    Aponeurotic layer
    Loose areolar tissue
    Pericranium
  6. 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
  7. You have been asked to assess the neurological deficit that might exist in a patient diagnosed with cavernous sinus thrombosis. You will focus your examination on cranial nerves related to the sinus that includes all the following EXCEPT:
    Abducens (CN VI)
    Facial (CN VII)
    Oculomotor (CN III)
    Ophthalmic division of the trigeminal nerve (CN V1)
    Trochlear (CN IV)
  8. The glossopharyngeal nerve exits the skull via what opening?
    Foramen ovale
    Carotid canal
    Jugular foramen
    Hypoglossal canal
    Stylomastoid foramen
  9. A person develops a cavernous sinus thrombosis. Because of its relationship to the sinus, which cranial nerve might be affected?
    Abducens
    Facial
    Mandibular V3
    Olfactory
    Optic
  10. 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
