Transcript

00:03

And here's your shmoop du jour brought to you by the optic

00:06

nerve the reason your big brother gets annoyed just looking at you... Alright [Little brother jumps on big brothers bed]

00:11

here's the question the place in the back of the eye where the optic nerve

00:14

leads the retina and has no rods or cones is called what and here are your potential

00:20

answers....Okay so the question is looking for a place in the

00:25

back of the eye with no rods and no cone let's keep that in mind as we look at our answers [A metal rod and an ice cream cone appear]

00:29

is this place where the optic nerve leaves the retina A; the fovea well the

00:35

fovea is a small pit in the center of the eye composed of closely packed cones [A construction man with two orange cones in the fovea]

00:39

it's responsible for sharp clear focused vision wait did we hear cones sorry

00:45

phobia this zone is a no cones allowed.. not to mention the whole back of the eye [Person crosses out 'back of the eye' and 'no cones']

00:50

thing so we can lose A...Everybody knows the back of the eyes where all the cool

00:54

kids sit...We meant bus what about C? Broca's area well that's a region of the [School kid sitting at the back of the bus]

01:01

frontal lobe but yeah okay already wrong frontal lobe is in your brain, not in [Hand points to man's brain and eye]

01:06

your eye but in case you're really curious its function is primarily linked

01:09

to speech production entirely unrelated to the discussion at hand but

01:13

responsible for our ability to have that discussion at all...So thanks Broca so

01:18

wrong but so right...Could it be D..well the lateral geniculate nucleus is a [Lateral geniculate nucleus shown in the brain]

01:24

structure in the thalamus that acts as the primary relay center for the optic

01:29

nerve in the thalamus.. not the back of the eye so D is out of the running and

01:33

E the optic chiasm is the part of the brain where the two optic nerves [Optic nerves shown crossing over in a diagram]

01:38

partially cross, again part of the brain not back of the eye... the brains really

01:43

making itself a pain today.. So we can cross out E as well so that means our answer

01:47

must be B, the blind spot which describes the part of the retinal wall [Car stutters down a road before parking]

01:51

within the eye so it doesn't have any cones or rods in order to make room for

01:55

the optic nerve to exit the eyeball this prohibits any light waves from being

01:59

transduced at that spot therefore creating a blind spot so B as in blind

02:04

spot is correct...A good thing we weren't blinding

02:07

the answer, right? [Man wearing an eyepatch]
