something that always seems to fail around big brothers here's our question [Big brother making little brother hit himself]

00:12

Amanda is suffering from a degenerative disorder that compromises muscular

00:16

function her doctor is recently prescribed a drug that will help improve

00:20

her condition by increasing the activity of the neurotransmitter associated with

00:24

muscle movement which neurotransmitter sites will the drug effect and here are the

00:29

potential answers .... Alright,let's begin with what we know we

00:35

know we're looking for a neurotransmitter thats related to muscle

00:38

function and we know that all of the above answers are in fact some of the [Man performing pull-up]

00:42

most common neurotransmitters or well maybe we didn't know that but hey we do

00:46

now so which one is it well it's not dopamine because we know that dopamine [Dopamine molecule]

00:50

is best known as the pleasure chemical when we experience stuff like tasty food [Girl taking a bite of food]

00:55

we get a boost of dopamine and while it might feel good to just say this is our

01:00

answer and call it a day, on this whole studying thing well that wouldn't be

01:04

right and who knows maybe figuring out the right answer will give us the [Dopamine kicks boy off his chair]

01:07

biggest dopamine kick of all.. Serotonin meanwhile can't be it either because

01:10

serotonin is most associated with mood it's a big contributor to well-being and [Girl waving her arms happily]

01:15

happiness but definitely not muscle movement although the muscle movement

01:19

required to lift spoon full of ice cream to your mouth is kind of definition of [muscular guy taking spoonfuls of ice cream]

01:22

happiness right norepinephrine isn't the right answer either as it deals with

01:27

stress hormones and the fight-or-flight response and while compromised muscle [little brother made to hit himself by big brother]

01:32

function can no doubt be stressful whether from a degenerative disorder or

01:36

a semi abusive older sibling it doesn't fit the bill and we get rid of E; GABA or

01:42

gamma aminobutryic acid which is wrong because it deals with the central

01:48

nervous system and specifically anxiety not muscle movement speaking of which

01:52

we're starting to get a little anxious here so let's move on to the right

01:55

answer which is D) acetylcholine which functions both in the peripheral nervous [Central nervous system and peripheral nervous system labelled on body]

02:01

system in the central nervous system as a neuromodulator in other [Man lifting weights]

02:05

a regulator and specific to our question helps regulate the movement of muscles

02:10

which is exactly why a doctor would prescribe a drug to help improve its

function no word yet on if said drug keeps away stronger older family members [muscular guy takes away big brother]
