00:00

Thank you here's Your shmoop du jour brought to you

00:05

by riddles about color For example what's black and white

00:08

and red all over zebra in a quentin tarantino film

00:14

Right here's our question The cells in the back of

00:17

the eye that only see in black and white are

00:20

called what And here a potential answers are going to

00:23

run right Well in order to narrow it down let's

00:26

take a look at what each part of the eye

00:28

does let's start with e the retinal ganglion cells it

00:32

looks like a made up phrase from a sci fi

00:34

film the return of the retinal ganglion but well it's

00:38

not that exciting These cells are responsible for transferring information

00:41

from the eye to the brain However since we're talking

00:45

about cells that see in some sense of the word

00:48

at least this answer doesn't fit it's not really doing

00:51

the seeing so much as receiving information from one source

00:54

and passing it along to another so in cross out

00:56

eat these retinal ganglion cells form the bulk of the

00:59

optic nerves along with the glial cells that regulate protect

01:03

and support the nerves as they do their information Sending

01:07

thing though is out as well It's like i let's

01:11

move on to see the bow via well the phobia

01:14

is a small pit near the center of the retina

01:16

That's responsible for sharp central vision providing us with direct

01:19

line of sight used in tasks like reading and driving

01:22

Think of it is you're focused vision or in other

01:24

words the number one thing you should be thankful for

01:27

your ability to reach the top of the scoreboards in

01:29

college duty But does it only see in black and

01:32

white know why Because this central pitting your eyes made

01:36

up of cones cones process color as well as visual

01:40

acuity so it looks like both cnn air out which

01:43

leaves us with b rods cones and rods are the

01:47

two types of cells that cover the eye and initially

01:49

received or see the light waves coming in The rods

01:53

handle the black and white which helps us see in

01:55

the dark so it looks like he's our answer But

01:58

don't worry rods Some of the best things only come

02:00

in black and white I'm gonna find these guys and

02:03
