Just started learning about the nervous system for psychology, i know this is aimed at more medical students but wow this taught me more in 11 minutes than my course has in 3 days! feeling confident now i can do more thorough research
Good overview, but it would have been nice to have at least touched on the different neurotransmitters specifically associated with the steps of transmission along each division of the system (e.g. metabotropically active muscarinic AChRs receiving ACh released by efferent postganglionic depolarization events in the PNS).
I had to search intestines on merriam bc he said it too many times and got it stuck in my head lol I don’t think I’ll forget this 😂 Great video!! Thanks!!
It's important to say that autonomic system consists of three main parts: somatic afferent pathway, central nervous system integrating complex and efferent pathway (that consists of parasympathetic and sympathetic pathways). At first I understood the begining of the video as if the autonomic nervous system consists only of efferent pathways and it's false. (source of my info : "an overview of the autonomic nervous system" PubMed)
My mind was boggled when I first started learning this, and that was as an EMT-B, the first level of entering into EMS. I had all kinds of trouble remembering that afferent means 'to' and efferent means 'away from' until I could recall they were talking about the brain as opposed to the ANS when efferent means it's coming TO the nerves and afferent means it's going away from it.
you state that PNS activation of the heart causes the heart is "pumping less hard and less often". My understanding is that the PNS innervates the nodes but not the ventricle. So the cardiac output goes down because heart rate goes down, but not inotropic effect.
Dear idiot there is CNS and PNS. CNS is your stupid brain and the Spine and PNS is the Somatic and Autosomatic explained above in the video. What is it you dont understand, is one of your synpses problem perhaps? Damaged neurons from birth? What was your apgar score at birth-ask your mom perhaps she knows about the mental disorders from birth.
I'm kind of curious why PNS has longer pre-synapse neuron. What is the reason behind that? Is it about how it functions? And about the difference between their neurotransmitter (acetylcholine and norepinephrine). Why are they different? If anyone can give me answers, that would be awesome. Thanks!
ill tell you what ive read, since PNS has long pre, it has short post, so the post fibers are not numerous and diverging like in SNS, which is good, we dont want generalized stimulation in PNS like in SNS, in PNS it can be fatal if its generalized stimulation. Makes sense ?
I get the numerous and diverging ends but still don't get idea of SNS has generalized stimulation. Sorry if I seem hard to understand hahaha. Thank you :)
Please forgive my ignorance on this topic, this is the first time I've learned about these two systems. I'm curious, I am diabetic and overweight, would it be best if I eat breakfast and rest a certain amount of time before doing any kind of cardio exercise and then wait for some time before eating again? It seems that if I eat and then immediately workout that it would be counterproductive.
Go to channels of dr. Eric Berg, dr. Jason Fung, dr. Ken Berry, dr. Sten Ekberg, dr. Mindy Pelz. They provide a lot of information on how to heal diabetes.
lol why did I have to read this comment now am finding it hard to concentrate on the lecture all am doing is listening for when he says intestines :,,,D
good video but the guy's vocal fry gets pretty annoying. not very hard to get rid of, and its not something you'd expect from a producer as established as khan.
I think 'Matthew' should watch this video. Matthew 6:25: “Therefore I tell you, do not be anxious about your life, what you will eat or what you will drink, nor about your body, what you will put on. Is not life more than food, and the body more than clothing?" Who is Matthew? The Bible editor? 1) To think about what we will eat or what we will drink is not 'anxiety', but it is useful for healthy life. 2) 'life' and 'food' are not things to be compared. To take food is a healthy thing to the life. 3) 'body' and 'cloth' are not things to be compared. To put on good cloth is a healthy thing for the body. 4) If Matthew will not agree with 1) to 3), he will be anxious about his life and his body.

It is aimed to understand mental disorders especially in neuropsykologi.
This guy is such a great teacher!! Love his videos
This clarified the PNS and SNS soooo much. Thanks a ton!
Nice video. He sounds a little bit like Cleveland in family guy :o
This teaches me not to read comments before finishing the video, now I can't keep focus!
I know right!!
Do you know how many times I needed to restart the video? :P
South Park is 1000 times better though
😂 facts...Now there is no way that I can't hear that lol
This was helpful! I like the term rest and digest..helped things click for me. Thank you!
I appreciate you being so organized
Thank you - that was well explained with great clear visuals.
You should have 1,000,000,000,000,000,000,000 subscribers. You are amazing
Patryk wasniewski ok
Yep
Patryk wasniewski alright
Fantastic! Great video! Love the simplicity of the subject, yet informative.
sir u are awesome.. i couldnt understand anything til now.. thnx alot!!
Thank you! This makes so much more sense now :)

Jackson Reynolds I was thinking just the same. I found it well explained but largely superficial. I do hope they will publish more in-depth videos
You are a life saver!! Thanks for the lecture

You're a great teacher. Thank you.
When you combine some of the stuff around kundalini theories with the parasympathetic nervous system there's some correlation going on.
Thank god I found this channel, it saved my day.
Excellent lecture. Thank you very much.

Thanks helped a lot
That was very helpful. Thank you :)
أفضل دكتور يدرس مر علي
You are the best teacher i have been watching
Oooo maaan, finally! Thank youuu!!!
Very Helpful. Thanks :)
Thank you soooo much. . You helped a lot
awesome summary. thnx.
Bless you guys
This video answered a lot of Q were in ma mind
I liked it a lot!
Thank u ❤️
Thank you.
great video!!!
A very big thanks ^^

Vicki Bee remember the term SAME...sensory for afferent...motor for efferent
You don't even have to take notes. He took the liberty of writting them for you! Thanks guy! That's One flashcard down...
It's not an excuse to get lazy
Aw man! Can't ever get a break. Tis true though
thank you for nice video
Thank you
Great!
How does the concept of chemical mediators in neurotransmission work, I mean the acetylcholine and noradrenaline?
Well done
Is computationalism reserved strictly for (personal level) cognitive activity or does computation happen in the autonomic systems?
Finally...!
another teaching hero
You f&$@ing rock. Thanks for this, man!
IntestineeeeeeeZZzz
:P
Intest[ai]ne makes me agitated 🤣
Great video, but intesTINEs... killing me!
Mark Harrison SAME HERE! 😭😂😂
omg! I could not focus on anything else except the intesTINES!!!
Can you please tell me where to find those images you have of the SNS and PNS?
while he said e-fer-ent, I was just saying eff-er-ent just to annoy myself. Very helpful and interesting video btw.
What software r u using?
brilliant

thank u
Feels like I'm listening to Dax Shepard lol. Thanks anyway
The autonomic nervous system involves afferent neurons also surely?
Don't confuse the lecture please

Great video, but unfortunately largely insufficient even at the paramedic level. Would have been nice to talk about neurotransmitters in more detail.

@@sandtx4913 Thank you, I'll do that.
'S' N S - 'Stress'
intestines hahaha
lol why did I have to read this comment now am finding it hard to concentrate on the lecture all am doing is listening for when he says intestines :,,,D
Grime thing I dont get it whats funny
ANS and PNS?!?
omfg i am at my 6 th year in medical school and i found this helpful !!! :P i am wrong ?
Whole lecture from 10 min 🤣🤣
Not good for LPN's only if your in a RN program I guess, he gets too in debt. I rather watch crash course.
good video but the guy's vocal fry gets pretty annoying.
not very hard to get rid of, and its not something you'd expect from a producer as established as khan.
What is that voice!!!but the video is nice
mint green sounds like Bert from sesame Street or squidward
instead of criticizing say thank you.
nice
thx
