to turn

orbital socket

where the eye sits in the skull

conjunctiva

clear membrane covering the front of the eye & inside surface of eyelids

sclera

white, opaque protective outer layer; provides a surface for the extrinsic muscles to attach to

cornea

clear area of the sclera that allows light to pass through into the anterior chamber

anterior chamber

the space filled with aqueous humor between the cornea & the lens

choroia

vascular structure of the eye providing blood & oxygen

pupil

opening that allows light to enter into the inner eye from the anterior chamber

Iris

colored ring of muscles that contracts/dilates according to how much/little light is present

lens

crystalline disc; focuses the light coming in through the pupil onto the retina

supersensory ligaments

connect the lens to the ciliary muscles

ciliary muscles

change the shape of the lens when the eye focuses on a nearby object

posterior chamber

space behind the lens; filled with vitreous humor

vitreous humor

thick, gel like substance that maintains the shape of the eye & aids in focusing light into the retina

retina

innermost layer at the back of the eye

rods

sensitive to low light; do not detect color; contribute to peripheral vision

cones

respond to bright light & color

optic disc

blind spot of the eye containing neither rods nor cones

optic nerve

receives signals from the retina & transmits them to the occipital lobe
