2
Know the location and function of the following
eye structures
sclera
This portion of the outer tunic is referred to as
the white of the eye.
3
This structure is clear, refracts light, and is
convex in shape.
Lens
4
This area is where the retina and the optic nerve
join contains no rods or cones blind spot
Optic disc
5
This area has the highest concentration of cones
the focal point of light needs to converge here
for the sharpest vision.
Fovea centralis
6
An inner tunic layer contains rods cones.
Retina
7
This structure regulates the amount of light
entering the eye.
Iris
8
Transparent, non-vascular structure most
anterior of outer tunic.
cornea
9
Floaters cast a shadow on your retina as they
pass through this
The vitreous humor
10
Night blindness is most commonly caused by a.
damage to the cornea b. damage to the optic
nerve c. an improper diet d. a toxic effect of
vitamin A
Why? Because of a LACK of vitamin A
11
Know the location and function of the following
ear structures
Auditory canal/tube
Auditory canal
This tube connects the middle ear to the throat.
Aka-the Eustachian tube.
12
Improperly blowing your nose could pass an
infection to which part of your ear?
The middle ear
13
Tympanic membrane
This structure- begins the middle ear the
malleus is attached to vibrates from sound waves.
14
Oval window
Oval window
The stapes vibrates this membrane attached to the
cochlea. Causing waves in the perilymph.
15
Auricle
auricle
The outer fleshy portion of the ear.
16
malleus
Auditory ossicle that is attached to the eardrum.
Passes the vibration to the incus.
17
Semicircular canals
Semicircular canals
An infection in this structure could cause
dizziness.
18
Put the following in order as light passes
through the eye.
vitreous humor
cornea
aqueous humor
lens
19
List the parts of the eye that light passes as it
enters the eye.
3. lens
1. cornea
2. aqueous humor
4. vitreous humor
20
What is the name of the natural pain suppressor
in the body? a. epinephrine b. adrenalin c.
endorphin d. encephalin
21
The scala tympani and the scala vestibule are
part of the a. middle ear b. vestibule c.
cochlea d. anterior chamber of the eye
22
Cross section through the cochlea
23
When these are distorted (bent) against the
tectorial membrane, an action potential is sent
to the brain.
Hair cells
24
Put the following in order that scents must
travel to reach the brain limbic
system olfactory tract cortex of temporal
lobe olfactory bulb
olfactory bulb- olfactory tract-limbic
system-cortex of temporal lobe
25
This gland is responsible for tear production? a.
lacrimal b. salivary c. cordoid coat d. ciliary
bodies
26
Which part of the brain deciphers taste? a.
temporal lobe b. parietal lobe c. frontal lobe d.
occipital lobe
27
Put the following events of hearing in
order The malleus moves the incus The tympanic
membrane vibrates The stapes pushes the oval
window The incus moves the stapes Sound waves are
channeled down the ear canal
1. Sound waves are channeled down the ear
canal 2. The tympanic membrane vibrates 3. The
malleus moves the incus 4. The incus moves the
stapes 5. The stapes pushes the oval window
28
Which general category of sensory receptors
detects variations in temperature? a.
thermoreceptors b. mechanoreceptors c.
photoreceptors d. pain receptors
29
The otoliths are located in a. the middle ear b.
the semi-circular canals c. the cochlea d. the
saccule in the vestibule
30
The receptors in the utricle and saccule are
stimulated when a. endolymph flows over the
spiral organ b. the otoliths bend cilia in
response to gravity c. the tympanic membrane
vibrates d. perilymph bends hair cells
31

come from regions far from the actual site of
pain is known as a. visceral pain b. phantom
pain c. referred pain d. somatic pain
38
Odors seem to fade away because of
Sensory adaptation
39
Treatment for cataract usually involves removal
of the a. cornea b. sclera c. lens d. vitreous
