Iris
a. The middle one of a chain of three small bones in the middle ear of humans
and other mammals
b. A structure in the cochlea of the inner ear that produces nerve impulses in
response to sound vibrations.
c. The dark circular opening in the center of the iris of the eye, varying in size to
regulate the amount of light reaching the retina.
d. Each of the second pair of cranial nerves, transmitting impulses to the brain
from the retina at the back of the eye.

changed.

Cochlea
Basilar
membrane
i. The innermost, stirrup-shaped bone of a chain of three small bones in the
middle ear of humans and other mammals, involved in the conduction of
sound vibrations to the inner ear.
j. A layer at the back of the eyeball containing cells that are sensitive to light
and that trigger nerve impulses that pass via the optic nerve to the brain,
where a visual image is formed.
k. A small depression in the retina of the eye where visual acuity is highest.
l. A membrane of the middle ear that vibrates in response to sound waves; the
tympanic membrane.
m.The transparent layer forming the front of the eye.
n. A transparent, biconvex structure in the eye that, along with the cornea, helps
to refract light to be focused on the retina.
16.
Organ of
Corti
Olfactory
Bulb
o. A spiral-shaped, fluid-filled inner ear structure; it is lined with cilia (tiny hairs)
that move when vibrated and cause a nerve impulse to form.
p. A flat, colored, ring-shaped membrane behind the cornea of the eye, with an
adjustable circular opening (pupil) in the center.
17.
Patterns
q. A repeated occurrence of a distinguishable nature.
18.
Constancies
r. A membrane in the cochlea that bears the organ of Corti.
