Sympathetic and parasympathetic (neuroanatomy)

[@jessica3609]

Just wanted to let you know that I learned in first second and third semester with your videos and successfully passed neuroanatomy because of you

[@nikeshra5216]

Don't joke I mean seriously..

[@loubainapeer9093]

Hubby: Who is that man? Me: my anatomy teacher But you haven’t even done science at O Level at school!!! Well.... that’s not stopping me from learning 😌 A little more than a year ago, I have been diagnosed with Fibromyalgia and from there on, I am slowly but surely learning about the systems in my body, how they work.... all that I had until some time back, taken for granted. I know that your video appeared in my feed because of the previous searches I have done regarding the human body and I am so glad it did. All that to say that I am not here for exams and some (well most) of the names and terms are lost on me but I am here to understand how our body functions and Sir you do a great job explaining all of that. Thank you very much. This video is a special one for me. Best wishes to you and to all your loved ones all the way from Mauritius. Stay safe everyone.

there’s a lot on the net about the importance of a healthy vagus nerve (s) and the effects of weak neck muscles C1 and C2, and a low vagal tone. it may help with your fibromyalgia. there are ways to improve the vagal tone (measurement of its strength). worth checking out. (I’m not a medical student either) I’m a reflexologist and we need to know anatomy etc. Knowledge is power! 😃

[@elisabethshoup5545]

Thank you so much for your channel. Voice/singing teacher here, and I’m so excited to find information that is not dumbed down for a target audience but that is also so clearly explained. This is the first time I’ve learned about this stuff and not also wanted to fall over. Also. “When you get used to explaining it you get really far away from learning it.” What a beautiful, refreshing, humble thing to hear a teacher say. Thank you.

[@studentmedicosi8222]

The best thing about your videos is they are concise, conceptual and easy to understand. Thank you for making anatomy easy and fun for us...

[@SamWebster]

Concise? Me?

[@marialondon1411]

i join the comments 2 likewise express huge gratitude and acknowledge your excellent teaching skills. you couldnt believe how far your teachings go. of all the the web i can confidently say that on your field u r simply the best sam

[@patriksvanstrom4130]

For a second there I thought the thumbnail was for a Dr. House video.

[@JohnSmith-zy1ur]

He needs to work on his House impression

[@ceresartico2493]

So so helpful. Great fan. I am a psychologist in Virginia, US, and using all this knowledge has helped my patients immensely. Particularly regulating anxiety and improving sleep. Cute daughter too 😄😍

[@adeelsajid995]

Amazing explanation! Thank you for making videos even during these times! I greatly appreciate you!

[@idkanything9371]

YOU ARE A GOOD MAN.... Yes, beat that quarantine like that.. we need you and LOVE YOU!

[@mm12]

This kind of videos should be the one going viral.

[@kingalexanderia3365]

Professor u r the best ever .... Please keep going always! Don't be late kindly.... we r missing u videos from time to another ........

[@okNusku]

Hi mate, I'm not student etc but have a big interest of the body. I'm a qualified PT (not what i do for a living but do train friends etc) but I am a runner (x20 marathons x10 ultras) like yourself. Love your uploads! Ive gained loads of knowledge from you so just wanted to say thanks, and carry on!!

[@vedantadas3830]

Thanks a lot for simplifying the complicated things so much.. Back in first year I had so much difficulty learning these basics... Now I'm in Final year of Medical School and learning anatomy again to understand Surgery

[@SamWebster]

Good luck with your surgical future. Lots of lovely detailed anatomy! You're going to learn so much more.

[@idkanything9371]

NEVER GIVE UP.... YES... cuz you were a little depressed in the last video.... WE LOVE YOU

[@f.g.k5669]

Thanks for your video. I was looking for explanation of Samp. and Paras. Nerve System and foun it very useful.

[@jilldickson4352]

I love your family, entertaining us in the background ❤️❤️

[@davereid-daly2205]

Sam, that was great teaching, it made me understand something very important ! Thanks Buddy 💫💥💯👌

[@vanshshahh]

I love your videos and I keep learning from you even after clearing my anatomy course. Could you please shed a little light on the embryology of the autonomic nervous system? It would really help to make the understanding of the ANS very intuitive!

[@bandanasharma5356]

Oh my God I am a literature student but biology is a subject which really fascinates me...sir I am from India I really loved your video the only problem I faced was to understand the English accent of your speech ....I will listen to the video many times....🙏🏻🙇namaskar...

[@bridgettep1486]

Hi Sam! Settling in for ur video can't wait to watch ✨🌠

[@anilakramer2054]

What a great video again, the way you explain it makes it so clear. The autonomic system is also very intriguing to my opinion!!

[@lighthouse1136]

I love your videos Sam! So inspiring! And entertaining lol. You're a fantastic teacher!

[@Amandeep-ei3gq]

All doubt solved sir... Please Make more video like this.. And #stayhomestaysafe

[@enlighteningknowledge5559]

you really make great videos. i have also just started making anatomy videos.wish i could be good at explaining like you

[@georgealderson4424]

Interesting as always sir. Thank you. I had a bilateral open lumbar sympathectomy in 1976 for ischaemia - I am a myelomeningocele - but was spared pain from the ischaemic areas because of my dodgy nervous arrangements! Unfortunately the same cannot be said for the surgical incisions! OUCH+++ Blessings and peace

[@sunshineandbs1263]

Sir, you did a very good job explaining it! This was very helpful! Thank you!

[@bosshugo5917]

You make the most awesome videos, love your vlogs too. I’ve learned quite a lot. Keep it up mate👍🏻

[@nb2028]

Thanks Sam for your expertise and sharing it with all! Do you have a process to understand and memorise these details?

[@SamWebster]

Just a lot of time and repetition. My top advice for my students is to use the language of anatomy and occasionally study together, describing things to each other and error checking.

[@nitikapoonia-pinkdentistry5424]

You are too good I loved your explanation Thank you so much

[@JamieScorer]

You’re videos are so damn helpful for uni study, keep it up you legend 👊🏼

[@glitzydebs]

Loving your stuff.thank you

[@byamugishagaraciano3115]

Very good professor

[@sbrebrown]

Another great video! You're on a neuroanatomy streak (which I love!). If you're looking for an isolation challenge, how about the minefield that is the limbic system :-)?

[@maryamrahmannia8502]

Love your videos

[@alexandrawachter8807]

Thank you - so well explained!

[@Espoirjehovanise]

Much respect the videos are heplfull

[@Diptikenjale542]

Can you please explain about this; Relaxation of lower esophageal sphincter due to vagal stimulation And contraction of LES due to muscarinic action i.e parasympathetic action

[@TheDentistryDiary]

Oh been waiting for this took me ages understanding this, video is great will make notes from it thank you :)

[@guitarrocker9848]

Heyy Sam i was wondering can u Please do a video on Dendrites.

[@elenaandrew8414]

You are amazing!

[@almahernandez7875]

Love your videos!

[@PikesCore24]

Question: Is breathing under autonomic or somatic control? Do the two systems overlap when it comes to breathing? Some people say that breathing is like a conduit into our autonomic nervous system because it is the only place where we can consciously affect our autonomic nervous system. I apologize if I'm being a bit vagusy here..

[@Vlog_Planet360]

Automatic

[@ruggerogabbrielli6831]

Brilliant video (as usual)! I have a couple of questions: Do heart rate and force of contraction always go together? I was wondering whether an increase/decrease in one had necessarily to imply an increase/decrease of the other (and vice versa)... Also, do all visceral afferents from the heart run back to the spinal cord with the sympathetic neurons?

[@SamWebster]

Heart rate & contractility: probably, although there may be an exception or two (there usually is in biology). A good physiologist will be able to explain this better than I can. Visceral afferents: no, many run back with the vagus nerve as the vagus nerve supplies parasympathetic innervation to the heart and the vagus nerve carries afferents back to the brain.

[@DamienMearns]

The sympathetic nervous system is very interesting therapeutically. The hardware for the sympathetic nervous system are the ganglion along the spine. A damaged spine from a trauma - even if the back has no pain - can cause merry mayhem all over the body. This site has a few short blog posts on this and how to fix it: goodback.co.uk/

[@evanwilliamson3602]

Hi Sam, great video. I have a diagnosis of Myalgic Encephalomyelitis (ME/CFS), and my autonomic symptoms are lack of sweat (haven’t sweat in 5 years), heart palpitations, raised heart rate upon standing (and sometimes dizziness/blackout). Any ideas as to what’s going on inside my body?

[@evanwilliamson3602]

And I’m always checking my bladder to see if I need to urinate, which is weird.

[@theplybons6852]

How can I get ahold of you...? I have some questions regarding facial nerves.

[@codieyoung1450]

you've always reminded me of tommy caldwell, but thought I'd mention it since I now know you're also a climber haha
