-
anterior chamber
fluid-filled space between the cornea and iris
-
aqueous humor
watery liquid secreted at the ciliary body-fills anterior and posterior chambers of eye-nourishes cornea, iris and lens
-
-
ciliary body
ring of muscle, controls power of the lens
-
ciliary muscle
smooth muscle portion of the ciliary body, near-vision capabilities
-
ciliary process
epithelial tissue-secrete aqueous humor
-
conjunctiva
mucous membrane that lines the eyelids and outer surfaces of the eyeball
-
cornea
bends light to focus image
-
eyelid (palpebra)
opens and closes
-
fovea centralis
- depression in the middle of the macula lutea
- sharpest vision here
-
macula lutea
central region of the retina, responsible for central vision
-
fundus (base)
interior surface of the eye ball: retina, optic disk, macula, posterior pole
-
meibomian glands
oil glands located along the rim of the eyelids
-
iris
- colored circle
- regulates light passage through pupil
-
lacrimal gland
secretes tears
-
lacrimal duct
tubes that carry tears to the lacrimal sac
-
lacrimal sac
structure that collects tears before emptying into the nasolacrimal duct
-
lens
bends and focuses light
-
lens capsule
capsule that encloses the lens
-
nasolacrimal duct
passageway for tears from teh lacrimal sac into the nose
-
optic disk
- exit site of retinal nerve fibers
- entrance/exit for arteries and veins
-
optic nerve
carries impulses of sight from the retina to the brain
-
pupil
center of the iris, light passes through here
-
retina
-cones & rods
- receives/transmits light to the optic nerve
- cones: color, bright light
- rods: dim light
-
