macular degeneration | lose central vision |
diabetic retinopathy | disease of the choroid (blood vessels) |

what parts of the eye do you see through | pupil, choroid, retina, sclera |
sclera | white of the eye -outer layer |
cornea | center outer layer of the eye. 1st layer that light travels through |
iris | a circular muscle that gives pigmentation |
choroid | blood vessels nerve sensation |
retina | layer where vision takes place- nerve impulse |
optic nerve | carries impulses to the brain |
cilliary muscle | can change shape of lens |
which structure gives most acute vision | fovea |
what sits inside the fovea | macula |
name the opening in the center of the iris | pupil |
state the pupil size in dim lights; bright lights | big/dilated ;little/constricted |
thin membrane which covers and protects eyeball | conjunctiva |
function of lacrim gland | forms tears |
location of the anterior cavity | cornea to back of lens |
location of the anterior chamber | cornea to iris |
location of posterior cavity | lens to back of nerve |
location of the posterior chamber | iris to back of lens |
function of the lens | focusing/accommodation |
location and function of the canal of schlemm | anterior cavity drains aqueous humor |
pathway light travel through eye | cornea, pupil, lens, retina, optic nerve, occipital lobe |
the three layers of the eye | sclera, choroid, retina |
the area of the brain in which vision occurs | occipital lobe |
refraction | bending of light |
ingredient of rods and cones | rhodopsin |
when light hits rhodopsin it splits into two chemicals | retinal & opsin which creates electrical stimulas |
specialized nerve cells that only respond to light are | rods and cones |
vitreous humor | jelly-like and is in posterior cavity |
aqueous humor | provides nutrients for all structures in the anterior cavity and picks up waste and gets rid of it too |
