Term
anterior chamber
Definition
fluid-filled space between the cornea and iris
Term
aqueous humor
Definition
watery liquid secreted at the ciliary bodir that fills
the anterior and posterior chambers of the eye an.
provides nourishment for the cornea, iris, and lens
Term
canal of Schlemm
Definition
duct in the anterior chamber that caries filtered aqueous humor to the veins and bloodstream
Term
choroid
Definition
vascular layer beneath the sclera that provides nourishment to the outer portion of the retina
Term
cilliary body
Definition
ring of muscle behind the peripheral iris that controls the power of the lens
Term
ciliary muscle
Definition
smooth muscle portion of the ciliary body, whicli contracts to assist in near-vision capability
Term
ciliary processes
Definition
epithelial tissue Foldson the inner surface of the ciliary body that secrete aqueous humor
Term
conjunctiva
Definition
joining together; mucous membrane that lines th. eyelids and outer surface of the eyeball
Term
cornea
Definition
transparent,anterior part of the eyeballcovering theiris,pupil,andanteriorchamberthatfunctions to refract (bend) light to focus a visual image
Term
eyelid (palpebra)
Definition
movable protective fold that opens and closes, coverins the eve
Term
fovea centralis
Definition
pinpoint depression in the center of the macula lutea that is the site of sharpest vision
Term
fundus (base)
Definition
interior surface of the eyeball including the retina, optic disk, macula, and posterior pole (curuature at the back of the eye)
Term
glands of Zeis
Definition
oil glands surrounding the eyelashes
Term
meibomian glands
Definition
oil glands located along the rim of the eyelids
Term
iris
Definition
colored circle; colored part of the eye located behind the cornea that contracts and dilates to regulate light passing through the pupil
Term
lacrimal gland
Definition
gland located in the upper outer region above the eyeball that secretestears
Term
lacrimal ducts
Definition
tubes that carry tears to the lacrimal sac
Term
lacrimal sac
Definition
struture that collects tears before emptying into the nasolacrimal duct
Term
lens
Definition
transparent structure behind the pupil that bends and focuseslight rays on the retina
Term
lens capsule
Definition
cansule that encloses the lens
Term
macula lutea (macula)
Definition
central region of the retina responsible for central vision; yellow pigment provides its color
Term
nasolacrimal duct
Definition
passageway for tears from the lacrimal sac into the nose
Term
optic disk
Definition
exit site of retinal nerwe fibers, as well as the entrance point for retinal arteries and the exit point for retinal veins
Term
optic nerve
Definition
nerveresponsiblefor carrying impulsesfor the senseof sisht from the retina to the brain
Term
posterior chamber
Definition
space between the back of the iris and the froni the vitreous filled with aqueous fluid
Term
pupil
Definition
black circular openin-e in the center of the iris through which light passes as it enters the eve
Term
retina
Definition
innermost layer that perceives and transmits light to the optic nerve
Term
cones
Definition
cone-shaped cells rvithin the retina that are color sensitive and respond to bright light
Term
rods
Definition
rod shaped cells within the retina that respond to dim light
Term
sclera
Definition
tough, fibrous, white outer coat extending from the cornea to the optic nerve
Term
trabecular meshworr<
Definition
mesh-like structure in the anterior chamber that filters the aqueous humor as it flows into the canal of Schlemm
Term
vitreous
Definition
jelly-like mass filling the inner chamber between the lens and retina that sives bulk to the eye
