[TheNUTRO247]

So why do we have ganglion in the ANS unlike the somatic?

[CzarThePlezer]

@TheNUTRO247 Because the somatic or voluntary pathway only has 1 afferent neuron that innervates skeletal muscle.

[re1ntyes]

@CzarThePlezer That is not much of an answer... Saying that it is so because the other pathway doesn't have it does not clarify anything: couldn't the preganglionic neurons just synapse directly onto the post~ ? And if not, why not. That is the question. For an answer, see TimmysMummy's answer below.

[CzarThePlezer]

@re1ntyes Actually it is an answer, maybe not as thorough as you would like it to be, but that's subjective

[19Tranc3r92]

@TheNUTRO247

One neuron can talk to more than one other neurons, therefore exciting and/or inhibiting multiple neurons at once. :)

[MrDevin666]

lol in high school and I think i'll be WAY ahead of the class from this. Is this university level?

[scanme214]

OMG i love you!!! now i see the light

[Noahthebeast09]

In the sympathetic pathway a preganglonic neuron is short and the postganglonic neuron is long, in the parasympathetic nervous system the preganglonic neuron is long and the postganglonic fiber is short they are not the same length as this figure shows.

[samachet]

@Noahthebeast09 But you see the different lengths on the global diagram, it expressly shows this difference, Watch again!

[bitterkei]

wish there were more lecturers like you!

this video is really helpful! =D

[mithhiji]

why do we have ganglia in ANS when it is not needed in somatic

[TimmysMummy]

@mithhiji I think its to make the mssg more general; neurons go to a ganglion & their message is picked up by lots of postganglionic neurons. so if we r in flight/flight mode, the general message is sent2 most of the digestive system 2 stop workin while we RUN. In somatic we only want to move certain muscles at a time... eg biceps to do biceps curls, If we had ganglions the message wld get all mixed up and sent to other muscles aswell so movement wouldnt be as precise just movement randomly!

[myalaynaangel]

Thanks, you cleared that up for me

ALOT!!

[aetdb]

hey could u tell me from what book are the graphics ???

[kyriacos08]

@aetdb I believe they are from Human Physiology by Fox

[islandiva13]

I really understand know the concept...Thanks

[jerYacoub]

Clarifies a couple of things. Thanks

[monesc]

tnx 4 d upload :-)

[SoDakSunshine]

you make that smacky noise with your mouth too much... but otherwise this is good.

[BartsDentist]

Perfec!

[marqbegay]

love it... thanks... sums it all up!!

[thewelshire]

Yeah I totally agree, the best explanation I've heard, thanks!

[sofiasalazars]

Great explanation!

[skyboy4299]

what book is this? The pictures are the best I've ever seen on this subject!!!

[dziekanek123]

8 minutes instead of 2h :)

[tc4101]

anyone know the answer to the question why autonomic we need 2 ganglions? something to do with the inhibitory?

[almalizette8907]

you are almost as good as my human physiology professor!

[jdeoliveira100]

I wish you were my pharmacology instructor! Very helpful :)

[theicecreamparlour]

Very helpful; made this topic a lot clearer, thanks!!

[dawnjimenez]

Very helpful, thanks!

[tigreletigre]

awesome, im a nursing student this helped a lot! thanks ;)

[Antwanete]

Thanks a lot
