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

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!!

[davidgonzalez]

Nice video. He sounds a little bit like Cleveland in family guy :o

[Amy-cbvt]

This clarified the PNS and SNS soooo much. Thanks a ton!

[paulchkreba]

This guy is such a great teacher!! Love his videos

[Prismarine_Man]

You should have 1, 000, 000, 000, 000, 000, 000, 000 subscribers. You are amazing

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).

[MsElina]

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)

You are the best teacher i have been watching

[MittenMom]

This was helpful! I like the term rest and digest..helped things click for me. Thank you!

[ClassPunkOnRumbleAndSubstack]

When you combine some of the stuff around kundalini theories with the parasympathetic nervous system there's some correlation going on.

You don't even have to take notes. He took the liberty of writting them for you! Thanks guy! That's One flashcard down...

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.

[altair]

sir u are awesome.. i couldnt understand anything til now.. thnx alot!!

[heznqeu]

This video answered a lot of Q were in ma mind

[christinevakas]

Thank you - that was well explained with great clear visuals.

[tfoprincess]

while he said e-fer-ent, I was just saying eff-er-ent just to annoy myself. Very helpful and interesting video btw.

[amygruber]

Thank you! This makes so much more sense now :)

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.
