A. incus

B. spiral ganglion

C. spiral organ

D. lateral lemniscus

E. cochlear nuclei - ✔✔A. incus

patient does not perceive the tone equally in the right and left ears, but

rather hears the tone louder in the right ear. When the vibrating tuning fork

is held next to the ears, it is heard much louder and longer on the left than

on the right. When the tuning fork is placed against the mastoid process on

the right side, the sound is heard. This patient suffers from:

A. conduction deafness of the left side

B. nerve deafness of the left side

C. conduction deafness on the right side

E. none of the above - ✔✔C. conduction deafness on the right side

A 28-year-old male in otherwise good health presents with loss of a portion

of visual fields in both eyes of 1 week duration. Detailed history of the

patient does not reveal any previous opthalmological or neurological

deficits. Visual field examination reveals Right Homonymous Hemianopsia.

Other aspects of the neurological exam were normal. In particular, pupils

were 2 mm in diameters, equal and reactive to light. There was no relative

afferent pupillary defect. Where are plausible sites in the visual pathway at

which a single lesion could produce the indicated visual field deficit?

(THERE MAY BE MORE THAN ONE CORRECT ANSWER)

A. Left Optic Nerve

B. Optic Chiasm

C. Right Optic Tract

D. Left Lateral Geniculate Nucleus

E. Right Optic Radiation in Temporal Lobe

F. Left Visual Cortex - ✔✔D. Left Lateral Geniculate Nucleus

F. Left Visual Cortex

A patient with homonymous hemianopsia and absence of the direct and

consensual pupillary light reflexes upon shining a small pin-point beam of

light onto only the blind half of either retina has a lesion in the:

A. optic nerve

B. optic chiasm

C. optic tract

D. optic radiation

E. primary visual cortex - ✔✔C. optic tract

A patient presents with a history of gradual loss of visual sensations from

only a limited area of the visual field. Temporally staggered neuroimaging

reveals a slowly enlarging mass in the right temporal lobe white matter.

This probable tumor is likely damaging:

A. projections to the right superior brachium

B. geniculocortical radiations to all of the right primary visual cortex

C. right loop of Meyer
