I wish i could give more than one like... This is the best ANS vid I've seen so far. Good job!!! From another med student here..

@kaztazable 11 лет назад

Please keep these videos coming! They really help me with understanding complex concepts.

@abukarshiqa6559 5 лет назад

Really very interesting topic of pharmacology many thanks for this lecture really appreciate your teaching methods,from Somalia medical student faculty of medicine.

@stephenram6933 9 лет назад

learnt more in 15 mins from your vid than 3 weeks in class.

@chillhaxx 11 лет назад

To be clear: the pancreas has alpha2 and b2 receptors. when norepinephrine binds to alpha2 (NE does not bind beta2) you decrease insulin release. However, epi can bind both, and when epi binds the beta2 it increases insulin release. BUT, there are more alpha2 receptors than there are beta2 receptors on the pancreas so the overall net effect of Epinephrine is its alpha2 effect (which is to dec insulin release). Hope that helps.

@NamGiaoSanJosebyQ 11 лет назад

its amazing . It helps me a lot more than a lecture in my class.please keep its up

@selasirhman9847 11 лет назад

In the comment who asked about the effect of PSN in the lung...the sympathatic work in the lung through beta 2 (which dilated the bronchus) on the other hand if in the video mistakenly sayed that the effect of PSN through beta 2 to constrict & secreation response....just get the idea of the PSN in lung is via muscurinic .... instead of saying muscarinic he sayed beta 2..so...you got the whole concept

@sunny1988u 10 лет назад

that`s synaptic vesicles...not seminal vesicles

@cplunajr745 6 лет назад

learning doctor yeah i was like whoa? But he’s allowed to make mistakes. Aren’t we all ? Hehe..

@F3ARL388 10 лет назад

Sympathetic preganglionic neurons are located T1- L2. Sacral parasympathetic ganglia are located S2-S4. I would use this vid as a review rather than a primary learning source due to mistakes.

@vaniaahmad2774 7 лет назад

F3ARL388 please mention what are other mistakes ??? kindly

@amclkk91 10 лет назад

nice job,,,,,,,i love pharmacology,,,,,,,,,,,,me aslo student of paramedical,,,,,,,,,,,,,,,,,

@SomalianSpeaker 9 лет назад

doesn't the skin sympathetic nervous system caused by Acetylcholine? then how does the it bing with alpha 1 receptor on skin? as we know acetylcholine only binds to nicotinic or muscrinic receptors ?? hmmmm i think there is something wrong there. Remember the Skin sympathetic response is the only exception that use Acetylcholine neurotransmitters. The acetylcholine released by sympathetic nervous system must bind to muscrinic receptors to cause dilation of sweat glands. anyone agree on this ?

@PeeedaPan 8 лет назад

+Abu Ibrahim Alhatimy yes, sweat glands in the skin that are innervated by sympathetic system have muscarinic receptors to bind Ach

@bindeeq4002 7 лет назад

Abu Ibrahim Alhatimy you are correct sweat gland is the only gland that is controlled by sympathetic through M3 receptor (he said alpha 1 = wrong)

@sthem2166 11 лет назад

Hi Doc, you made a mistake- the beta 2 receptors in the lungs are stimulated by the sympathetic nervous system not parasympathetic.

@tiptopked2974 10 лет назад

the ganglion isn't a a bunch of "nerves" but a bunch of neuronal cell bodies located in the PNS.

@sarasami4451 9 лет назад

thank you very much for your effort in these lectures >>>> God to bless you DR.

@habibibrahim4748 9 лет назад

VERY CLEAR VEDEO AND GOOD SIMPLE EPLANATION ,,THANKS ALOT

@ngwiramd9067 11 лет назад

Where is the lecture on cholinergic drugs doc. These video are just too good to miss any of them

@bklyngurlie718 11 лет назад

People use fight or flight b/c it is the best example to cover most things logically, but you also say it is for stress. Pregnancy is a stress on the body and you eventually want to reduce that stress by having the baby...hope that makes sense

@tonycamer8189 9 лет назад

Really really good. ....excellent job. Thanks. ...

@anikixvi 10 лет назад

Thank you soooo much! i've been trying to study the sympathomimetics and cholinergics and further into pharma without a solid understanding of the ANS, thank you! saved my underexamination A**!!! Hopefully will be following you from now on ^_^

@sjqureshi6034 8 лет назад

very amazing lecture.. i have a confusion ...beta 2 receptor activation cause relaxation of pregnant uterus, that is why beta agonist with selective action on uterine muscles are used to avoid premature labour... you said the opposite on 35:01... please correct me if i am wrong

@romeomavuso2105 8 лет назад

Thanks for the memorising tricks 1st year medical student from South Africa

@Aadi-zoi97 8 лет назад

yes the sympathetic innervation of skin use acetylcholine. ...

@rafalalhilaly7757 8 лет назад

thank u for this great video =)) I wish u teach us in my college !

@priscillavarela1822 5 лет назад

great lecture, I almost said "bless you" when he sneezed lol

@elizabethalvarez485 9 лет назад

This Guy explained all my class and he wasn't there, lol. Good teacher, the video was very animated too. Thanks

@rahulnayak6553 9 лет назад

This video has been the foundation for my pharmacology. I cannot thank you enough! But you're wrong about insulin, @ 44:45 It is a hypoglycemic hormone, it converts glucose to glycogen and it prevents lipolysis. What you told are the functions of Glucagon.

@juveriakhanam1568 7 лет назад

vasoconstriction is by alpha1 right and u said that the vasodilation is by beta 2. (both are adrenergic receptors) .Then when an adrenergic neurotransmitter is release what will happen?

@ebangoosa 10 лет назад

You were right the first time! Stimulation of beta-2 does cause insulin release (beta 2 release insulin after a meal). However, the overall result of adrenergic stimulation on insulin is inhibition because of alpha dominance (alpha-2 stimulation= insulin release inhibition cuz when you are running you need all the glucose you can get for energy and insulin will deplete you glucose). Source: My pharmaco notes and wiki.

Im so glad to find this

@SuperDestiny2015 11 лет назад

i didn,t understand the effect on lung.PNS binds to beta2 receptors? can any body explain that pls

@hemantchavan4018 8 лет назад

thanks it was easy to understand

why the sound is mono?

@shrikantpandya1994 9 лет назад

Alpha 2 - inhibits insulin secretion Beta 2 - augments insulin secretion

why dont you give your100 pharma lectures made easy for free. we cant pay u but we wil pray for u

@thetradingpharmd 11 лет назад

Quick question doc, which book are you using for your lectures??

@carmenluisaguerra74 9 лет назад

He explains it so nice

@shahajanbaig919 6 лет назад

yes

@chelsisoliva4116 9 лет назад

excuse me sir. hehe. i thought insulin(beta) is the one that facilitates the conversion of glucose to glycogen and it decreases the blood sugar level. while the glucagon(alpha) facilitates the breakdown the glycogen to glucose, increases the blood sugar level. (confused :/)

@FilipinoZeroFighter 9 лет назад

chelsi soliva not exactly convert glucose to glycogen but more on increase uptake of glucose... that's what i remember.

@moadham1767 7 лет назад

WRONG..we give B2 Agonist to treat hyperkalemia by producing insuline from pancreas..thats mean b2 agonist increases the insuline ..you said it redeuces the insuline..or not so ?

mistakes about Mydriasis This is the work of Sympathetic nerves on the IRIS (the center of the pupils) . If you get high on Amphetamine, every one notices your pupils WIDE Miosis: When the IRIS makes the Pupil hole Puntiform or very relaxed iis due to stimulation of the Parasympathetic nerves High on Opioids

@mashrurakunjo 5 лет назад

Thank you so much for this video. I was in a pinch just 1 hour before my pharma class test on ANS, because the material wasn't going through my head😢😅. Then i found this and aside from being really easily described, the whole presentation was so full of humor😂 it really eased me. Thanks again! Please make more.

@Fenaki15 10 лет назад

That was very helpful for our credit test ! THANK YOU!!! YOU SAVED US FROM FX!! :)

@samkriven 11 лет назад

i find you very intelligent...i love your video..i am a registered nurse and just now i fully grasp the topic...you're the best,..tis will help me a lot.. @ftplectures

@samsaleh8643 10 лет назад

It was really good that you explained, "fight or flight" and "rest and digest" early in the video. It helped me predict what responses you were going to next reveal.

@livelywell 10 лет назад

Nice and thanx

@garimaphulauriya6867 10 лет назад

Best sir .. and the confusion that was due to mistake about parasympathetic nervous system in lung is also clear now .. thank you sir foe the best lecture.

@sophie8977 10 лет назад

Could somebody please tell me, if this is a good rapid review lecture for someone who is preparing for USMLE step 1?

@CactusHub 10 лет назад

Thank you for making me understand the autonomic nervous system, please can you try and do a video on the four plexus, cervical,brachial, lumbar and sacral anatomically and physiologically
