AUTONOMIC NERVOUS SYSTEM; PART 1 by Professor Fink.wmv
Вставка
- Опубліковано 21 кві 2012
- This is Part 1 of Professor Fink's Autonomic Nervous System Lecture. This Video Lecture introduces the Autonomic Nervous System (ANS), describing the functional anatomy of the Parasympathetic (Cranio-Sacral) Division and then the Sympathetic (Thoraco-Lumbar) Division. Professor Fink then COMPARES & CONTRASTS the autonomic neural innervation of the visceral organs with the somatic motorneuron innervation of the Skeletal Muscles. Reference is made to Dual Innervation, Rest & Digest State, Stress State, fight, flight & freight, Automaticity, Myogenic, Neurogenic, Acetylcholine (ACh), cholinergic nerve fibers, Norepineprhine (Norepi), adrenergic nerve fibers, muscarinic & nicotinic Cholinergic Receptor Sites, and Adrenergic Receptor Sites. In addition, Professor Fink defines the terms ganglion, preganglionic, postganglionic, and identifies which Cranial Nerves contain parasympathetic (preganglionic) autonomic
nerve fibers [the Oculomotor (III); the Facial (VII), the Glossopharyngeal (IX) and the VAGUS (X)] and which spinal nerves contain sympathetic (preganglionic) autonomic nerve fibers.

as i learn from your lecture , so you are my teacher and the best teacher i ever had in medicine studies,,,,,
BAMMMMM! A+ in this class thanks to Dr. Fink! So greatfull to him.
I wish we have a professors like Dr. Fink! That is so amazing how easy to understand this complicated system thanks to you. Thank you very much!
Respected Sir,
I am a Master of Arts Yoga Student in India , So I have Human anatomy and physiology as subject. When I started to learn anatomy , I was getting confused . But After watching your video , I am highly impressed with you . You are doing a great work and helping students around the world .
Well done professor Fink!!!!!!!!!!!!!!!!!!!!
wish Professor Fink is my lecturer, so easy to follow his lectures because he's clear and delivers with so much energy :D
Lecture Outlines by Professor Fink can be purchased from the WLAC Bookstore on-line. The LINK is posted at the bottom of the Video DESCRIPTION above.
Thank you so much prof! I wish I was taught by you when I attended university. You made it so simple and easy to understand. Thank you again..
God Bless you Professor Flnk. You are a teacher's teacher! Thank you!
NUMBER ONE PROFESSOR IN THE WORLD!!!
I got the pieces from my anatomy class.. but you laid the foundation and put the pieces together. I appreciate how you refer back to older pages to draw that connection. Fantastic lectures.
Thank you for making learning fun! Keep up the great work of teaching us these amazing bodily functions.
Number one prof in the field
This the best A&P class ever! Thank you so much for sharing your awesome lectures on utube! I finally understand what my book is trying to tell me!
I'm already in love with your lectures, not only clearing concepts also getting interest in the subject. Thank you soooooooo much Professor.. ^_^
Thank you so much for all of these videos!
I wish you were my anatomy professor! You are such a GREAT teacher! THANK YOU!
Fabulous Fink...wish you taught at my med school! Thank you so much for making your classes available online.
Love your video and the way you teach. Oh and the changing of the voice. This system is complicated in class and reading the book its like a manual. Thanks for recording your lectures.
Great job, professor!!! Thank you.
THANK YOU!!!!!! Its all so clear now.
Wonderful! I am so blessed because your powerful lecture helps me so much understand about the hard part of the nervous system. Even though one semester ended, still lots of questions left and my mind was wandering to find something else....
It is so helpful and thanks for your online lecture for free.
I just love the second voice he makes
magbene konneh
He makes me laugh every time. 😆
thank you lord for this man,seriously i wish you were my professor,you explain it a lot better...THANK YOU SO MUCH Sir.
These videos are the best! Thank you, Professor Fink!
Well, maybe not all the yelling for those suffering from hpx. Uncomfortable.
You must be one of those who live in a sad world where dandelions and leaves in the lawn scream at you with their deafening silence. Get over it. It's called life. Go outside and tell all the traffic to stop because the motors are just too much for you. I suffer from agetophobia from people like you.
Very simple presentation-Excellent!
I really wish you were my professor because you make it so simple and enters easily in student's mind. My professor works with slides (by reading it) and that makes such an amazing course so boring. Thank you to make it so nice again. You are the best, I am sure!
I say! Your UA-cam username is incorrect. Let me fix that...
*HeroFink*
There we go. Much better.
Yes Hero Fink is correct 😍😍😎😎😘😘
True he is amazing
Thank you Professor.
professor Fink you are the BEST!!
beautiful lectures....thank u so much
Thank you!
God blessed you
Thanks professor Fink.
On the picture where it shows the sympathetic and parasympathetic lines going to the different organs, are those only in relation to the specific cranial nerves that effect the parasympathetic nervous system?
Thank you, sir.
My God, can I adopt you ???!!! I love your lectures!!!! - Medical Student :)
thanx Dr.fink
i looooooove you
youve explained every thing i didn`t understood
thank you thank
i really mean it thank you :')
Hello Professor,
so What I don't understand is : how come the Ach neurotransmitter is released in the sympathetic nerve at the pregnaglionic fiber and then it becomes Noreepi postganglionic fiber ?
thank you Professor
Might have missed this during the video but does the sympathetic and parasympathetic neurons only function under as visceral motor neurons or are they also somatic motor neurons as well?
Dr. Fink I love you.
You forgot another part of ANS: the Enteric system. The ANS is subdivided into sympathetic, parasympathetic and enteric system.
❤❤❤
I like how he changes his voice when describing some terms lol
Butterfliesnest its great
looooove you thanks alot💕
These things you mentioned: Iris of the eye, tear glands, mucus glands, salivary glands, etc etc, are these the things that are said to be controlled by the autonomic NS?? Answer may be obvious, but I want to know exactly what the autonomic nervou system is.
Is there a physiological reason why the myelinated preganglionic fibers of the parasympathetic is significantly longer than the myelinated preganglionic fibers of the sympathetic?
wow i am so happy. he explains well.
Is computationalism reserved strictly for (personal level) cognitive activity or does computation happen in the autonomic systems?
Thanks !
Amazing teacher
Why is it important that there is a difference between muscarinic and nicotinic ACh Rs if they can both be activated by Acetylcholine??
:) sarap mag aral! Toink..
Has someone bought the outhands? Wich is the best?
Another great lecture,thanks! I have a question: You showed paper, in there we see autonomic innervation of heart. Does Vagus.N go through the spinal cord? Because in the paper parasymphatetic neurons, that innervate heart, are localized in spinal cord ( we can see dorsal ganglion). I checked multiple times, but it seems so, Vagus n. doesnt go through spinal cord. Can you answer pls?
No vagus nerve is a 10th cranial nerve,ie it originates from the brainstem .Since it doesn't originate from spinal cord,therfore will not go via spinal cord.
IS THERE ANY WAY TO GET ANY OF THE HANDOUTS HE USES FOR THESE LECTURES??
you are my awesom.
great :)
wooow fantastic lecture!!! can i find this sheets somewhere ?
What happens to the amount of receptors of post synaptic nerve terminals if a nerve is denervated or severed? Do the receptors increased in number or decrease?
There will be an increase in number of Receptor Sites (called "up-regulation"). Anytime there is a decrease in the amounts of the signal molecule (neurotransmitter or hormone) there is increased synthesis of Receptor Sites and increased sensitivity to the signal molecule. Anytime there is an increase in the amounts of the signal molecule (neurotransmitter or hormone) there is a decreased synthesis of Receptor Sites (called "down-regulation") and decreased sensitivity ("resistance"), such as what occurs in Type 2 Insulin Independent Diabetes mellitus.
Thank you so much
Thank you very much prof❤❤ , prof I have question why is preganglionic fibers of sympathetic much shorter than parasympathetic preganglionic fibers
The sympathetic preganglionic fibers are shorter perhaps because most synapse in the sympathetic chain ganglia, which is next to the spinal cord. In contrast, most parasympathetic preganglionic fibers are longer because they synapse in ganglia near the visceral organ they innervate. IN OTHER WORDS, for ANATOMIC (& embryological) reasons.
wow!!
cool stuff
From what my book shows me, the heart's baroreceptors will sense an increase in BP, the glossopharyngeal nerve transmits signals to the medulla oblongata (integrating ctr) then the Vagus nerve transmits inhibitory signals to cardiac pacemaker, which the effector (heart) decreases the BP. I'm not understanding how you have this reflex from the heart going to the spinal cord?
The "medulla oblongata (integrating ctr)" LOWERS the BP by sending signals along parasympathetic autonomic motorneurons (in the Vagus Cranial Nerve X) to the SA Node pacemaker. HOWEVER, to INCREASE the BP (when it is too low), signals are sent along sympathetic autonomic motorneurons (contained in spinal nerves) to the SA Node.
Ok, thanks for explaining. I had drawn your picture from your lecture, and my instructor said it was incorrect, that's why I was somewhat confused.
great
?According to your presentation, if we already have nicotine produced in our heart muscle which activates the parasypathetic nerve. Is it the case that when individuals smoke nicotine that it over stimulates the heart and increases the level of nicotine in the blood circulation. Which I would imagine creates craving and can over stimulate the heart. I have noticed that individuals that crave for a cigarettes, that they almost appear to have a panic attack causing an increase in their heart rate. Would like clarification on this. Could it be that the tobacco industry is aware of this fact ? If the case is this not an ethical issue?
The human body does NOT produce nicotine. The Receptor Sites are called "nicotinic" only because nicotine was found to activate them (but not the "muscarinic" Sites) many years ago. So the terminology is arbitrary.
So we have like five nervous systems?
wish you were my professor! mine is so dry and doesn't explain in an interesting way.
life saver, hero !! i've been looking for such a clear and exciting explanation for so long !!!! thank you so much professor seriously you cant even imagine how much this is helping
Thanks that was great, Ill summerise all this tomorrow and watch the 2nd part :)
i had an ache on my influenced ears when you hit the seat with ground LoL
we use the headphone lol
Hello professor, I really want to buy your pharmacology outline hardcopy and I contacted the bookstore 2 or 3 weeks ago but didn't get any response. I will really appreciate u help me. Thank you in advance.
I have e-mailed Mr. Nilhson Zelaya [ZelayaN@wlac.edu ] about this and hope to hear back from him. Please e-mail to me [FinkS@wlac.edu ] your e-mail.
thank you so very much. And thank u for fast response 🙏🏼
Hi prof.
its me again. I emailed you couple of days ago and waiting for the reply.
Sorry to bother you and thank you in advance.
Why would facial muscles have autonomic motor neurons??
they don't
professorfink
Do you talk about the substantia nigra in one of your lectures??
2nd not every organ has dual systems, for example the adrenal and sweat glands on,y have sympathetic nerves. It's also not true that parasympathetic is more active at rest, just that the sympathetic kicks in higher under stress otherwise it's an equal balance.
Prof Fink states that "IN GENERAL" organs have both parasympathetic and sympathetic (at ~5:40), and also only then states that the parasympathetic system is the dominant influence at rest, not that it's more active.
That is just semantics because that was the context of what he was trying to say. Dominant means it's more active, how else do you measure activity sheesh? You can't compare one chemical to the other. For example NE vs. choline. But you can compare % increases perhaps. Either way I'm sure he hasn't. And I'm also sure this is so rudimentary it's pointless.
you are such a tool. this man is great and your knowledge of physiology is as weak as your guitar skills
Ooo. Your language speaks volumes about your character.
who ever this is.. you're not helping nor understanding.. stop confusing people. I assure you, everything he said in the video is correct. go find some one else to blame.
This are medical lectures or nursing ???is it helpful for medical students bcos I dnt see all topics are covering frm this video
These lectures were presented to students pursuing Nursing, Respiratory Therapy, Occupational Therapy, Dental Hygiene & other Allied Health Degrees.
I wondered if there was a difference too. But based on how he teaches I’m not sure you’re missing many details. But I’m not an md
Unfortunately he has stated main false things in this lecture. Just as an example there is no such thing as an autonomic motor neuron or nerve. Large somatic neurons control motor functions
Super terrific R what do you call the smooth and cardiac muscles and vagus nerves by which they communicate by.
Dove Love the vague nerve is a parasympathetic Autonomic small fiber nerve and it is not a motor nerve. Muscles are muscles not nerves and Autonomic nerves in no way control muscles, they control blood flow and sweating but not muscles.
Lol. I actually thought there was some dumb Jock in the audience who didn't do his homework.
The worst part is when he talks about receptors in the heart. He completely skipped over breaking down the ganlia then was confused about muscarinic
