stirrup

Front

A tiny U shaped bone that passes vibrations from the anvil to the cochlea (inner ear)

Back

eardrum

Front

Auditory canal goes to ear drum; sound waves vibrate; channels sound

Back

inner

Front

auditory tube (middle or inner)

Back

anvil

Front

A tiny bone that passes vibrations from the hammer to the stirrup

Front

external acoustic canal (outer)

basilar membrane

Front

lines the inner wall of the cochlea and runs its entire length; the different flexibility allows different areas to vibrate more intensely when exposed to different sound frequencies

Back

cones

Front

Respond to color Operate best under high illumination

Back

inner

Front

oval and round window (middle or inner)

Back

cornea

Front

Clear membrane that is the outer part of the eye; curved which bends light on the surface in order to focus on the back of the eye

Back

Fovea

Front

Densely populated with cones vital to many visual tasks Contains ONLY cones Blind spot

Back

Iris

Front

Colored part of the eye;
