Here's your shmoop du jour brought to you by pickles which are a

00:07

pretty big dill in the sandwich community.. deal, dill.. whatever here's our [sandwich chomping at a pickle and the pickle runs off]

00:12

question.. Bill thinks pickles taste awful ..which of the following is

00:17

responsible and here the potential answers... well while it

00:22

might seem like we're dealing with someone who can't see reason but since [Boy blindfolded attempting to hit a pinata]

00:25

we're actually dealing with is taste Bill's sense of taste in particular

00:30

bearing that in mind we should probably eliminate any answers that have nothing

00:33

to do with it starting with three that sound a lot like they don't.. See what we did

00:37

there rather hear what we did there all right look the incus is one of three [diagram of the ear's incus]

00:42

small bones in the ear that make up the ossicles they transmit vibrations from

00:46

the eardrum or tympanic membrane into the inner ear ending up in the cochlea

00:50

a snail shaped structure that houses the organ of corti which is a tiny little [man playing the organ in the inner ear]

00:55

organ that a man in corti plays in your ear.. yeah na, na, na, na, naa..

01:01

as cool as that would be we're just pulling your leg on the organ playing guy there.. It

01:05

actually produces nerve impulses in response to sound vibrations.. Good vibr-

01:10

okay stop.. So unless Bill somehow connects the taste of pickles to the [man eating a pickle]

01:14

sound they make while being eaten these can't be our answers so that leaves us [Bill distressed at a man eating a pickle loudly]

01:20

which is B and C immediately one of these should be standing out as

01:24

incorrect hint it's the one with the word olfactory in it, okay maybe that

01:28

name is obvious olfactory refers to your sense of smell and the olfactory bulbs [image of an olfactory bulbs]

01:32

of a first place where scents entering your nose get transduced into neural [smell being transduced in the nose]

01:36

information sure smell and taste are closely related that's why you can't

01:40

taste anything when a cold wreaks havoc on your sinuses. Bill this isn't quite [Bill with a cold attempting to eat a pickle]

01:45

what we're looking for but we're actually looking for is B..papillae

01:49

which are the bumps on the tongue each containing about 50 taste buds that's a [a microscope image of papillae of the tongue]

01:54

lot of buds, even if we don't have that many buds and we're super popular when

01:58

these bumps are messed with your sense of taste gets messed up that's really [a drop of coffee lands on a tongue]

02:02

the only explanation we have for Bill not liking pickles he must recently have

02:06

burned his tongue on something hot right? that's got to be it so yeah the answer

02:10

is definitely B.. B as in Bill what's wrong with you pickles are freaking

02:13
