Question | Answer |
PHOTORECEPTORS= | detect changes in light |
RETINA= | contain photoreceptors/innermost layer of eyeball |
CHOROIDS= | middle layer of eye,great blood supply |
SCLERA= | white of eye,continues as dura matter |
FOVEA CETALIS= | contains all cones |
MACULSA LUTEA= | contains fovea centralis,contains mosly cones |
LACRIMAL GLAND= | superior-lateral side of eye,produces tears |
IRIS= | colored part of eye |
LENS= | changes shape,(rounder bulges) light waves bend @ a sharper image |
PUPIL= | hole in the middle of iris,where light enters the eye |
AQUEOUS HUMOR= | fluid in the anterior cavity,between the lens and cornea |
VITREOUS HUMOR= | fluid in posterior cavity,helps keep shape of the eyeball(between the lens and retina) |
CORNEA= | avascular,no blood supply,continues w/sclera/most anterior part of cornea |
CILLARY= | intrinsic eye muscles |
CONJUNCTIVA= | membrane that covers outside of eyeball-except the cornea(pink-eye) |
CATARACT= | clouding of the lens |
RESTING AND DIGESTING OF ANS SYSTEM= | parasympathetic |
FIGHT OR FLIGHT SYSTEM OF ANS= | sypathetic |
CERUMEN= | ear wax |
CLAUCOMA= | increases pressure in the eye (aqueous humor does not drain) |
REFRACTION= | bending of light waves |
BLIND SPOT= | optic disc (where the opti nerve leaves the eyeball) |
MYOPIA= | nearsightedness(focus in front of the retina) |
HYPEROPIA= | farsightedness(focus in back of retina) |
ASTIGMATISM= | cornea is misshaped |
ORGAN OF CORTI= | receptors for hearing |
MYDRIASIS= | sympathetic stimulation |
OPTIC DISC= | blind spot,no rods or cones(optic nerve meets the eyeball) |
