Rods, cones and retina

Question 1

Rods

Answer 1

bipolar photoreceptors
black and white vision
more sensitive to light than cones

Question 2

rods found

Answer 2

all over retina besides fovea

Question 3

rods protein

Answer 3

rhodspin

Question 4

rhodspin turns into ___ and ___ when struck by light

Answer 4

ospin and retinal

Question 5

retinal can be converted into

Answer 5

vitamin A

Question 6

in absence of light retinal and ospin turn into

Answer 6

rhodspin

Question 7

light causes rods to

Answer 7

hyperpolarize

Question 8

dark/light adaptation

Answer 8

in dark room–> increase in available rhodspin so eyes can adjust to light

Question 9

when rods not stimulated they are

Answer 9

depolarized

Question 10

Cones

Answer 10

bipolar
responsible for vision and visual acuity

Question 11

cones found in

Answer 11

fovea and macula
fewer in rest of retina

Question 12

as light intensity _____so does our ability to see color

Answer 12

decreases

Question 13

cones protein is

Answer 13

idospin

Question 14

three types of idospin

Answer 14

red
green
blue

Question 15

color interpretation is possible to due

Answer 15

overlap of idospin

Question 16

pathway

Answer 16

cone/rods–> bipolar cells–> ganglion cells –> optic disk

Question 17

optic tract

Answer 17

some project to opposite side
some project to same side
