Vision, Olfaction, and Gustation

Visual fibers pass to this structure to activate pupillary light reflex

• Pretectal nuclei

• Superior colliculus

• Suprachiasmatic nucleus

• Ventral lateral geniculate nucleus

Affectation of this pathway causes inferior quadrantinopsia

• Optic chiasm

• Optic nerve

• Optic tract

• Parietal fibers of optic radiation

• Temporal fibers of optic radiation

Retinal is converted to Vitamin A during this adaptation

• Dark to light

• Light to dark

Efferent nerve of Corneal reflex

• CN2

• CN3

• CN5

• CN7

for conscious perception and analysis of olfaction

• Less Old Olfactory System

• Very Old Olfactory System

• Newer Pathway

Taste from the base of the tongue passes through

• CN 7

• CN 9

• CN 10

the anteromedial portion of temporal lobe is the only area of the entire cerebral cortex where sensory signals pass directly to the cortex

• False

• True

Which is not part of the Less old olfactory system?

• olfactory bulb

• olfactory tract

• anteromedial thalamic nucleus

• amygdaloid nuclei

Optic nerve fiber from the temporal halves of the retina cross in the optic chiasm

• False

• True

Third order neuron for gustation is found

• Postcentral gyrus

• Thalamus

• Tractus solitarius
