Q

vascular layer 4 functions

A

provides eoule for blood vessels and lymphatics that supply tissues of eye,
regulates amount of light entering eye,
secretes and reabsorbs aqueous humor that circulates within chambers of eye,
controls shape of lens, which is essential to focus

Q

Lens (lens fibers) are filled with… that provides…

A

crystallins, which provides clarity and focusing power to lens

24
Q

Lens (cataract)

A

condition in which lens has lost its transparence

25
Q

aqueous humor

A

fluid circulates within eye

26
Q

Intraocular pressure other name

A

Glaucoma

27
Q

Intraocular pressure

A

fluid pressure in aqueous humor,
helps retain eye shape

33
Q

ciliary body extends

A

posteriorly to level of area serrata

34
Q

(ciliary body) serrated..

A

anterior edge of thick, inner portion of neural tunic

35
Q

ciliary body contains

A

ciliary processes and ciliary muscle that attaches to suspensory ligaments of lens

36
Q

outer layer from inner layer eye called

A

Digmented part

37
Q

inner layer called

A

neural part (retina)

38
Q

inner layer contains

A

visual receptors
associated neurons

39
Q

inner layer types of photoreceptors

A

Rods and cones

40
Q

Rhods

A

see black and white,
do not discriminate light colors,
highly sensitive to light

41
Q

Cones

A

see colors,
provide color vision,
Densey clustered in fovea, at center of macula

42
Q

…% of all sensory receptors in eye

A

70%

43
Q

role humain eyes sensory system

A

see, perseve and recognize things

44
Q

function of cornea

A

lets light into eye

45
Q

difference rods and cones in retine

A

rods detect light intensity/ function in low light,
cones perceive color / works better in bright lighting

46
Q

how does the afterimage effect work

A

occur due to overstimulation of photoreceptor cells,
stare too long at a color -> cells become fatigued -> temporary opposite color image when you look away

47
Q

layers of eyeball

A

retina
iris
choroid
lens
sclera
cornea

48
Q

retina function

A

contains photoreceptor cells

49
Q

iris function

A

controls pupil size/light entering

50
Q

choroid function

A

supplies blood/absorbs excess light

51
Q

lens function

A

fucuses light onto retina

52
Q

cornea function

A

transparent front cover

53
Q

sclera function

A

protective outer layer

54
Q

optic nerve role in vision

A

leads signal into the brain so you understand what you see

55
Q

how is the optic nerve formed

A

bipolar neuron connects the other neuron that formes optic nerve

56
Q

why see different colors when looking at an afterimage?

A

cause photoreceptor cells are tired so they create an opposite color perception

57
Q

a lot or not layers the eye

A

many layers
