Cornea, Iris, Pupil, Lens, Ganglion Cells, Bipolar Cells, Rods and Cones

The process of transducing a light signal into a neural impulse

Involves interpretation of visual cues that indicate how near or far away objects are

Clues about distance based on the differing views of the two eyes

Objects within 25 feet project images to slightly different locations on the right and left retinas, so the right and left eyes see slightly different views of the object

Involves sensing the eyes converging toward each other as they focus on closer objects

clues about distance based on the image in either eye alone.

Involves images of objects at different distances moving across the retina at different rates (fence posts compared to trees in distance while driving in car)

clues about distance that can be given in a flat picture

Consists of the pinna and the eardrum

A sound collecting cone

A taunt membrane that vibrates in response. (waves of pressure create vibrations)

Vibrations of the eardrum are transmitted inward by mechanical chain- three tiniest bones in the body(Hammer, anvil, and stirrup) known as the ossicles.

Converts relatively large movements with little force into smaller motions with greater force

A fluid filled, coiled tunnel that contains the receptors for hearing

Runs the base of the spiraled cochlea, and holds the auditory receptors.

Perception of pitch corresponds to the vibration of different portions, or places, along the basilar membrane (hair cells at various locations respond independently and to different frequencies)

Perception of pitch corresponds to the rate, or frequency at which the entire basilar membrane vibrates. (the whole membrane vibrates in unison in response to sounds)

Locating the source of a sound in space.
