00:15

here we go The snail like structure that houses cells

00:17

capable of picking up sound waves is called the what

00:20

And here are answers All right well so we're looking

00:25

for something that looks like a snail and picks up

00:28

sound waves and by picking up we don't mean using

00:30

cheesy one liners picking up means receiving and probably sending

00:34

information from sound waves not just being affected by sound

00:37

waves Now that we have that covered we might as

00:39

well follow along with a sound wave is it enters

00:42

a near we'll call you rattle by bumming a ride

00:45

from him will probably find the answer to our question

00:47

No time sound good so let's see after entering the

00:51

outer ear and heading up the ear canal rattle here

00:54

meets the ear drum or temp tannic membrane of your

00:57

oval window there from the middle ear to the inner

01:21

ear But seeing as none of these bones nor this

01:24

oval window looked like a snail or possess special cells

01:27

from picking up those waves you'll none of them have

01:29

the answer to the question either Once these vibrations have

01:32

traveled along those three bones known collectively as the bosic

01:36

als and passed through the oval window they reached the

01:39

snail life Qalqilya The cock leah is a bunch of

01:44

lines with a basil remembering that contains hair cells That

01:49

work is receptors for hearing The movement of these hair

01:52

cells translates into neural information or is transducer effectively telling

01:56

the brain what we're hearing in this case it's the

01:59

neighbor kid blasting his dubstep but boring him Sorry qalqilya
