d. contains corticobulbar fibres lying most anteriorly
e. fibres fan out as the corona radiata in the medullary centre
92. The olfactory nerve:
a. is the first cranial nerve
b. is associated with smell
c. carries parasympathetic fibres
d. contains bipolar cells
e. traverses the cribiform plate of the ethmoid bone
93. The anterior visual pathway:
a. consists of third order neurons
b. begins at the cornea
c. terminates at the lateral geniculate nucleus
d. receives its blood supply from the posterior cerebral artery
e. uses GABA as an excitatory transmitter
94. Regarding the visual pathway:
a. the nasal retinal ganglion cells are less densely packed
than the
temporal retinal fibres
b. the inferior nasal fibres decussate in the anterior optic chiasm
c. in 10% of people the optic chiasm lies inferior the pituitary gland
d. the posterior and middle cerebral arteries supply the visual cortex
e. the peripheral inferior retinal fibres run in the outer part of
the
Loop of Meyer
95. The visual pathway:
a. 60% of fibres decussate in the optic chiasm
b. the internal carotid artery lies lateral to the optic chiasm
c. junctional scotomas are produced by compression of the fibres in
the anterior knee of Wilbrand
d. the magnocellular pathway synapses in layers 3 to 6 in the
lateral geniculate nucleus
e. approximately 25% of the fibres leave the optic tract to connect
in
the superior colliculus and pretectal area
