1. A large malignant tumor of bone invades the floor of the middle
cranial fossa. Knowing the anatomy of the middle cranial fossa, you
look for symptoms that would indicate tumor invasion in all of the
following structures, except:
A. foramen spinosum.
B. internal auditory meatus.
C. foramen lace rum.
D. foramen ovale.
E. foramen rotundum.
2. A patient suffers from a dry and painful right cornea, numbness of the right nasal cavity as well as a loss of sensation along the right
side of the palate in the oral cavity. Which of the following could be the cause of these symptoms?
A. a small tumor pressing on the trigeminal ganglion.
B. a growth in the pterygopalatine fossa that compresses the pterygopalatine ganglion.
C. a loss of cell bodies in the pterygopalatine ganglion.
D. compression of the geniculate ganglion.
E. a tumor that compresses the structures in the superior orbital fissure.
3. The following statements about the drainage of the paranasal sinuses are correct, except:
A. The sphenoid sinus drains into the sphenoethmoidal recess.
B. The maxillary sinus drains into the middle meatus.
C. The frontal sinus drains into the inferior meatus.
D. The posterior ethmoidal sinus drains into the superior meatus.
E. The anterior ethmoidal sinus drains into the ethmoidal infundibulum/middle meatus.
4. Each of the following statements regarding veins in the head and neck is true, except:
A. The retromandibular and facial veins unite to form the common facial vein.
B. The external jugular vein lies superficial to the sternocleidomastoid muscle.
C. The internal jugular vein is formed by the union of the inferior petrosal and sigmoid sinuses.
D. The straight sinus is formed by the union of the superior and inferior sagittal sinuses.
E. The facial vein lies superficial to the submandibular gland in the submandibular triangle.
6. Your room mate finally indicates that he has been rather subdued
because he has had a persistent headache for about two weeks.
Having Just started your ophthalmology clerkship, you examine his
eyes and find that he has bilateral papilledema (edema of the
optic disc) and congested retinal veins. You immediately suspect
some intracranial pathology that has increased his cerebrospinal
fluid pressure. The reason for your diagnosis is:
A. Since the retina is an outgrowth of the brain it reflects all neuropathology of the brain by developing papilledema.
B. Since the optic nerve is covered with the meninges, an increase in the pressure of the cerebrospinal fluid will compress the optic nerve and the venous drainage of the retina leading to papilledema.
C. Since the opthalmic artery is so small, increased intracranial pressure compromises blood flow through it as it enters the orbit.
D. Since the vitreous humor communicates with the subarachnoid
space, its pressure rises when cerebrospinal fluid pressure rises.
