Neurology | Adrenergic Receptors

[@Ag_paul]

It's like Prof Zack actually shrinks himself into a tiny being, drive into the body systems and studies whatever is happening there, comes back and give us a report... Because man this is sooo realistic... How many textbooks would i need to go through to understand this 🥲 God bless you Professor 🙏 You've saved a lot of people in the med sch

[@scratchthesurface3138]

Dude, it's a joy to see you explain this, but it's even more of a joy to see you smiling with such passion about it all. I'm smiling with you in equal awe. It's inspiring my man, keep it up.

[@prasadkonda7833]

Great explanation. Thank you

[@ash.toronto31]

Its his passion!

I'm constantly amazed by the quality of this channel. It's incredible to think that people voluntarily produce better lessons than my MedSchool. Congrats and thank you

by far the best and most detailed adrenergic lecture I've experienced, even professors in med schools stumble through these

[@michellejordan5241]

I am so impressed with your extensive knowledge. AND you are very good at communicating it in a very understandable way. For us auditory learners... all I have to do is listen to your lectures and everything makes total sense.

[@virnan]

Holy crap you are the light shining into the dark corners of my brain. You have solved the mystery of the receptors in the body for me. Why couldn’t a rest book simply tell me that beta 2 are inhibitory and alpha 1 excitatory. I cant believe how you made it logical for me. Thank you.

[@tomandlizzy]

OMG!!!!! Why did they not teach this in my paramedic class!!!! I have a MUCH better understanding of adrenergic receptors now. My new goal now is to change the way paramedic students are taught. If they are taught the why rather than just rouge memorization we will produce much better medics and save many more lives. It makes me SICK when I am on shift studying and I hear a seasoned medic tell me you will never need to know that.

[@maryamamir5561]

You are gifted to teach things that most of the people can't. Thanks for the videos.

[@andrewjames2294]

Awesome video! Just to clarify, A1- in smooth muscles of blood vessels for contraction therefor inhibition and in organs for activating peristalsis such as in ejaculation. In addition to that they increase contraction in sphincters for inhibition, A2- in Beta, Alpha cells of kidneys, platelets, and neurons. B1- in JG cells, Nodes, and Ghrelin secretion. B2- opposite of A1, relaxes in smooth muscles of blood vessels in activated organs for fight or flight. And in organs it relaxes such as to prevent peristalsis. They are also for activation of organs that need to secrete stuff in fight or flight such as salivary glands and liver. B3- is for adipose tissure and bladder only. I hope someone clarifies this. Thanks!

Thanks a lot, you are awesome ! just one comment to add at 4.37 it is norepinephrine which has higher affinity to Alpha-1 receptor than Epinephrine.

[@clintonodinaka6737]

Not at all epinephrine >norepinephrine

​@@clintonodinaka6737 No. The guy's right. It's in the textbooks. NE has higher affinity to alpha-1 and epinephrine has higher affinity to alpha-2

I’m a huge fan, currently doing my non medical prescribing course. When the tutor was explaining this my brain started to hurt. You communicate it better.

[@ruthstewart5242]

Thank you SO much for these videos. These are important concepts that I really want to UNDERSTAND not just memorize and you make that possible while also making it interesting, engaging, and fun. As a paramedic studying for critical care, I have found several of these videos to be the PERFECT level of depth. I suddenly understand shock in my patients in a way I didn't before and this has set the stage for me to much more easily understand how various vasopressors work (via another one of your videos of course!). So thank you for producing these, thank you for providing such high quality education for free, and I'm off to check out your memberships because I'd love to support the work you do.

Excellent fight or flight organ recital! Perfect ending with how chronicity effects dangerous risk factors for emboli…😎👍

[@zviizaks]

First of all thank you for your wonderful lectures. I think there is a small mistake in this lecture. N.E has higher affinity to alpha receptors than EPI.

[@libramoon3269]

I just checked the book, it says, NA is equipotent to Adr, on alpha receptors, but it is shown to be less potent as in the test systems as it is reuptaken faster.

[@yusufkarim100]

Zviizaks, you are right. N. E. stimulates only the Alpha receptors, 100% Alpha. It has no Beta stimulation at all. Epinephrine has 50% Alpha and 50% Beta stimulation. So it can stimulate both Alpha and Beta receptors. Epinephrine and N. E. are both naturally occurring catecholamines. But there is a synthetic catecholamine called Isoprenaline, which is 100% Beta receptor stimulant. To sum up N. E. - 100% Alpha Epinephrine - 50% Alpha + 50% Beta Isoprenaline - 100% Beta

[@dr.faridatef1516]

Dear sir, Thank you for the great illustrations. Just couldn’t catch up on 3 parts: 1- while B2 is stimulatory, how does it inhibit the A2 cells in pancreas in order to inhibit Glucagon release? 2- while B2 is stimulatory, how does it inhibit the Mast Cells in Bronchi? 3- finally, A1 wasn’t detailed in Uterus. What does it exactly do there? With big success wishes

[@Mariam-zz5wy]

A1 receptors in the uterus cause constriction to the uterus that is basically all what you have to know but it isn't really that important
