Which of the following is most related to phantom limb pain?
photoreceptor
adaptation
projection
accomodation
Which of the following receptors adapt most rapidly?
receptors that detect blood chemistries
olfactory receptors
pain receptors
nociceptors
Which of the following is most related to the spinothalamic tract, thalamus, and nociceptors?
hearing
speech
pain
sight
Which of the following describes the basis for referred pain (e.g., the pain of a heart attack radiates to the left shoulder and arm?
Myocardial enzymes from the injured heart muscle diffuse into the shoulder region
The same blood vessels that supply the myocardium also supply the shoulder and arm
The same nerves that carry sensory information from the heart also carry sensory information from the shoulder
Nociceptors are found only in the axillary region
All the extrinsic eye muscles
determine pupillary size
move the eyeball in the socket
refract light waves
change the shape of the lens
Which of the following is not true of the retina?
dependant on the choroid for oxygenation and nourishment
contains the photoreceptors
is the nervous layer of the eye
covers the optic disc, making it the area of most acute vision
The malleus, incus, and stapes
are inner ear structures
are located within the semicircular canals
contains the organ of Corti
are ossicles located in the middle ear
What happens at the optic chiasm?
Aqueous humor is secreted
Rods and cones are stimulated
Vitreous humor is drained from the posterior cavity
Fibers of the optic nerve of each eye cross and project to the opposite side of the brain
When drainage of the canal of Schlemm is impaired
lacrimation ceases
Intraocular pressure increases
The person develops presbyopia
a cataract forms in the affected eye
Which of the following is most associated with the rods?
color vision
macula lutea
fovea centralis
night vision
What is the result of contraction of the radial muscles in the eye?
The eyeball looks toward the sky
The eyeball looks toward the nose
Mydriasis
The eyelid opens
Which of the following refers to the reflex ability of the lens to change its shape as an object moves closer to the eye?
accomodation
adaptation
projection
presbyopia
Because the pituitary gland is located behind the optic chiasm, a pituitary tumor is most likely to cause which condition?
cataracts
a disturbance in vision
error of refraction, such as myopia
conjuctivitis
Which of the following is least descriptive of the organ of Corti?
mechanoreceptors
Eustachian tube
choclea
inner ear
Which of the following is a balance- related inner structure?
Semicircular canal
organ of Corti
Eustachian tube
cochlear nerve
The primary auditory cortex
receives sensory input from CN II
Is located in the temporal lobe
is called Wernicke's area
initiates the nerve impulses that move the eyeball
The eustachian tube connects the
throat with the pharynx
pharynx with the middle ear
organ of Corti with CN VIII
stapes with the eustachian tube
What term is used to describe the choroid, ciliary muscle, and iris?
meibomian
uvea
canthus
lacrimal apparatus
Nociceptors
respond to wave motion
detect pain
are found in the nose
are stimulated by light
The structure that is not part of the retina is
fovea centralis
rods and cones
macula lutea
choroid
The layer that supplies blood to the retina is the
sclera
conjunctiva
rods
choroid
This condition is the result of impaired drainage of aqueous humor through the canal of Schlemm causing increased interoccular pressure
detached retina
cataracts
strabismus
glaucoma
The vestibule and the semicircular canals are structures that function in the sense of
touch and pressure
smell
hearing
balance
Hair cells are
found in the cochlea and the semicircular canals of the ear
are stimulated by fluid motion
mechanical receptors
all of these are true of hair cells
The receptors for smell and taste are
chemoreceptors
mechanoreceptors
sour, sweet, salty, bitter
nociceptors
Acommondation is the ability of this structure to change its shape.
lens
iris
cornea
pupil
The tympanic membrane
separates the middle ear and the inner ear
transmits sound from the ear ossicles to the inner ea
vibrates in response to sound waves entering the outer ear
is connected to CN VIII
The fovea centralis and macula lutea
secrete the aqueous humor
are associated with rods and night vision
form the optic disc
have a high concentration of cones
