regulate the amount of light reaching the retina

covers iris, provides most of the eyes optical power and focuses light, protects the eye, provides stru

Fluid that is constantly produced and drained to nourish the eye and maintain its shape

muscle, colored portion of eye, with an adjustable circular opening, the pupil in the center, that regulates the amount of light that can enter the eye

helps bring rays of light to focus on the retina

Fills two-thirds of the eye between the lens and the retina and provides a path for light to reach the retina.

receive images produced by the lens and triggers nerve impulses that pass via the optic nerve to the brain.

exit point for nerve fibers from the retina to the brain, no rods or cones

sensory fibers that transmit sight impulses to the brain.

where rods/cones are, Processing the visual information from the center of our field of view, helps to minimize light scatter and improve the accuracy of visual signals, and the ability to process fine details contributes to our sense of depth perception.

Helps maintain shape, size, and also forms a tough, protective outer layer that shields the delicate internal structures of the eye

How does the eye transform light energy into neural messages?

phototransduction, Rods/cones convert photons into chemical + electrical signals, processed by other neurons in the retina before traveling down the optic nerve to the brain, where they are interpreted as images

peripheral vision, black and white, movement

the outer ear, the visible part of the ear (opening unto the head) that protrudes from our heads (design to catch sound waves) It direct sound waves into the ear canal (auditory canal)

The eardrum, Sound waves make the eardrum vibrate

Sound waves travel to vibrate the bones (auditory ossicles) of the ear

A coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses on the basilar membrane.

Idea that different parts of the inner ear detect different sound frequencies. High pitches are sensed near the entrance, low pitches near the end.

We hear pitch based on HOW FAST the hair cells vibrate

A theory of pitch perception proposing that groups of auditory neurons fire in rapid succession, or "volleys", to encode the frequency of sounds above 1000 Hz.

cornea	covers iris, provides most of the eyes optical power and focuses light, protects the eye, provides stru
aqueous humor	Fluid that is constantly produced and drained to nourish the eye and maintain its shape
iris	muscle, colored portion of eye, with an adjustable circular opening, the pupil in the center, that regulates the amount of light that can enter the eye
Lens	helps bring rays of light to focus on the retina
Vitreous humor	Fills two-thirds of the eye between the lens and the retina and provides a path for light to reach the retina.
retina	receive images produced by the lens and triggers nerve impulses that pass via the optic nerve to the brain.
Blind spot	exit point for nerve fibers from the retina to the brain, no rods or cones
optic nerve	sensory fibers that transmit sight impulses to the brain.
Fovea	where rods/cones are, Processing the visual information from the center of our field of view, helps to minimize light scatter and improve the accuracy of visual signals, and the ability to process fine details contributes to our sense of depth perception.
