Anatomy of the eye

Question 1

How many layers are in the eye?

Answer 1

5

Question 2

What is perception

Answer 2

based off neural firing
is different for everyone

Question 3

visual stimuli and visual receptors

Answer 3

human visual range is extremely narrow
visual stimuli is inherently ambiguous

Question 4

visual field

Answer 4

what we see in front of us (left and right)

Question 5

visual sensitivity

Answer 5

the neurons ability to detect levels of light
(more sensitive can detect in dim light)

Question 6

visual acuity

Answer 6

high resolution (due to cones)

Question 7

visual transduction

Answer 7

the conversion of light into neural signals

Question 8

what is an advantage of having one eye on each side of your head?

Answer 8

larger visual field

Question 9

what is an advantage of having both eyes in front?

Answer 9

higher visual acuity

Question 10

Binocular disparity

Answer 10

the difference between 2 retinal images helps create 3D and depth perception

Question 11

Pupil

Answer 11

allow light to enter

Question 12

iris

Answer 12

the muscle that give eye color and regulate the size of pupil (dilation)

Question 13

lens

Answer 13

accommodates by changing width allowing light to be focused for the retina

Question 14

retina

Answer 14

biological receptors (light rays converted into neural signals)

Question 15

fovea

Answer 15

located in the back of the eye, highest visual aquity, center of field of vision.

Question 16

macula

Answer 16

contain fovea

Question 17

blind spot

Answer 17

no receptors in the blind spot (only has the axons from retinal cells)

Question 18

optic nerve

Answer 18

carries the signal to the brain
