Questions
why is bile important? - Correct Answer ✔️✔️bile helps digest fats
how does the gall bladder get rid of bile? - Correct Answer ✔️✔️the gall
bladder contracts, releasing bile via the common bile duct into the duodenum
through the duodenal papilla
5 special senses - Correct Answer ✔️✔️olfaction, taste, vision, hearing,
equilibrium and balance
where is the olfactory pathway located? - Correct Answer ✔️✔️on the
temporal lobe of the cerebral cortex
what is the pathway of odor the olfactory cortex? - Correct 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) - Correct Answer ✔️✔️taste
,Where are taste receptors located? - Correct Answer ✔️✔️deep in the
grooves of taste buds
what are the 6 primary taste sensations? - Correct Answer ✔️✔️sweet,
salty, sour, bitter, umami, and water
describe the gustatory pathway - Correct Answer ✔️✔️taste goes to taste
receptors->CHs->medulla->gustatory cortex
What are the two nerves associated with the gustatory pathway? - Correct
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 - Correct Answer ✔️✔️3
what kind of connective tissue makes up the outer layer of the eyeball? -
Correct Answer ✔️✔️dense connective tissue
what kind of connective tissue makes up the middle layer of the eyeball? -
Correct Answer ✔️✔️loose connective tissue layer
what kind of tissue makes up the inner layer of the eye? - Correct Answer ✔
️✔️nervous tissue layer called retina
,what is the sclera and where is it located in the eye? - Correct Answer ✔️✔
️white sheath that protects the eyeball; fibrous tunic that surrounds the eye
what is the cornea and where is it - Correct Answer ✔️✔️its the
transparent anterior continuation of the sclera that protects the lens
its AVASCULAR (therefore it can be transplanted)
what is the choroid? - Correct 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 - Correct 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? - Correct 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? - Correct Answer ✔️✔️inner layer of nervous tissue
within the eye that contains photoreceptors (rods and cones)
, What are rods and where are they found? - Correct 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? - Correct 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? - Correct Answer ✔️✔️the
middle layer
