Which of the following is not true of a general sense organ?
They are grouped in a localized area.
Another term for the eardrum
Tympanic membrane
A condition where the lens of the eye becomes milky in appearance and loses its transparency is called:
a cataract
The sense of smell is classified as:
a chemoreceptor
The olfactory receptors:*
also assist in the sense of taste
The eardrum is:*
also called the tympanic membrane
The rods in the eye:*
are used to see in dim light
The external ear is called the:*
auricle aka pinna
Which of the following is not true about the senses of taste and smell?
both respond to four primary stimuli
The sense of taste is classified as a:
chemoreceptor
Which of the following is not part of the choroid layer?
cornea
Which sensation is not sensed by a general sense organ?
equilibrium
The part of the eye with the highest concentration of cones is the:
fovea centralis
An increase in pressure inside the eye is called:*
glaucoma
The cells responsible for the sense of taste are the:
gustatory cells
The perilymph is:
inside the bony labyrinth

is classified as a mechanoreceptor
The vitreous humor:
is found in the posterior chamber
The cornea:*
is the clear part of the sclera in the front of the eye

mechanoreceptor
This is a functional characteristic of all sense organs:
must be able to detect a stimulus, must be able to detect a change in the intensity of the stimulus and must be able to change the stimulus into a nerve impulse

photoreceptor
The "farsightedness" of old age is called:*
presbyopia
The choroid layer:*
prevents the scattering of incoming light rays

respond to the colors red, green, and blue and are part of the retinal layer
The innermost layer of the eye is the:*
retina
The white part of the eye is called the:*
sclera
The sense of balance occurs in the:*
semicircular canals and the vestibule
The vestibular nerve contains a nerve from the:
semicircular canals and the vestibule
