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

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
