cow eye 😭😭😭😭😭😭😭😭

allows us to focus on objects that are close or far away

cornea

causes eyeshine

tapetum lucidum

converts light information into electrical signals that can be sent to the brain

retina

dark membrane between the sclera and retina

choroid coat

fat tissue

adipose tissue

filled with smooth muscles that contract and relax to change the size of the pupil

iris

focuses incoming light directly on the retina

lens

goopy gelatinous fluid inside the eye maintaining the shape of the entire eye

vitreous humor

hard flattened sphere behind the cornea

lens

has a curved surface that bends light

cornea

lines the orbit (eye socket) to cushion the eye

adipose tissue

maintains the shape of the cornea

aqueous humor

membrane at the back of the internal eye filled with photoreceptor cells

retina

membrane that wraps around the outside of the entire eye up down left and right in order to look different directions

extraocular muscles

muscles on the outside of the eye

extraocular muscles

not found in humans

tapetum lucidum

opening in the center of the iris

pupil

opening that get larger or smaller to control the amount of light that enters or exits the eye

pupil

photoreceptor cells that are capable of color vision

cone cells

photoreceptor cells that cannot detect color

rod cells

photoreceptor cells that function in a light environment

cone cells

photoreceptor cells that function when light levels are low

rod cells

reflects light backwards in the eye to improve vision when light levels are low

tapetum lucidum

rich in blood vessels in order to provide nutrients to the retina

choroid coat

shiny bluish greenish portion of the choroid coat

tapetum lucidum

tough and clear layer at the front of the eye (window of the eye)

cornea

transmits visual information from your eye to your brain

optic nerve

watery fluid between the lens and cornea

aqueous humor

white of the eye

sclera
