5 special senses - (answer)olfaction, taste, vision, hearing, equilibrium and balance
where is the olfactory pathway located? - (answer)on the temporal lobe of the cerebral cortex
what is the pathway of odor the olfactory cortex? - (answer)odor goes to the olfactory receptors, pass
through cribriform plate of ethmoid bone, CN I synapses on neurons in olfactory bulbs, whose axons
form olfactory tract, and then goes to the olfactory cortex
gustatory (definition) - (answer)taste
Where are taste receptors located? - (answer)deep in the grooves of taste buds
what are the 6 primary taste sensations? - (answer)sweet, salty, sour, bitter, umami, and water
describe the gustatory pathway - (answer)taste goes to taste receptors->CHs->medulla->gustatory cortex
What are the two nerves associated with the gustatory pathway? - (answer)Facial nerve (CN VII):
anterior 2/3 of tongue
Glossopharyngeal (CN IX): posterior 1/3 of tongue
how many layers of the eyeball are there - (answer)3
what kind of connective tissue makes up the outer layer of the eyeball? - (answer)dense connective
tissue

what kind of tissue makes up the inner layer of the eye? - (answer)nervous tissue layer called retina
what is the sclera and where is it located in the eye? - (answer)white sheath that protects the eyeball;
fibrous tunic that surrounds the eye
what is the cornea and where is it - (answer)its the transparent anterior continuation of the sclera that
protects the lens
its AVASCULAR (therefore it can be transplanted)
what is the choroid? - (answer)layer surrounding the eye that contains blood vessels that supply oxygen
and nutrients to the tissues of the eye
what is the ciliary body , where and what does it do - (answer)anterior continuation of the choroid,
contains smooth muscle (ciliary muscles) that controls the shape of the lens for focusing an object
what is the iris and what is its primary function? - (answer)the iris is smooth muscle surrounding the
pupil, giving eye color and changes pupil size to regulate amount of light entering/exiting eye
what is the retina? - (answer)inner layer of nervous tissue within the eye that contains photoreceptors
(rods and cones)
What are rods and where are they found? - (answer)-receptors activated by dim light
-used for night vision
-black and white vision
-used for peripheral vision
--found in the retina
What are cones and where are they found? - (answer)-receptors activated by bright light
-used for daylight vision

-color vision
-used for central vision
--found in the retina
what layer of the eye is the choroid located? - (answer)the middle layer
what layer of the eye is the sclera located in ? - (answer)outer layer
what layer of the eye is the ciliary body located? - (answer)middle layer
are the cornea and the choroid in the same layer of the eye? - (answer)no, cornea is in the outer layer
and the choroid is in the middle
during sympathetic stimulation, what happens to the iris/pupil? - (answer)fight or flight/ pupils will dilate
during parasympathetic stimulation, what happens to the iris/pupil? - (answer)rest and digest stage;
constrictors contract and pupil gets smaller
what is the transparent gel located in the posterior cavity? - (answer)vitreous humor
what is the vitreous humor made out of, and when is it produced? - (answer)transparent gel thats 99%
H2O, not produced until 4-5 years old
what are floaters (in terms of the eye)? - (answer)detached cells you can see in your vision
whats so important about vitreous humor? - (answer)creates proper pressure within the eye and helps
keep retina in place, maintains vision
