Alpha and beta receptor action made simple!
HTML-код

- Alpha and Beta receptor drug properties are discussed within this video. Always remember you have ONE heart, TWO lungs. Alpha always constricts, Beta always dilates. There are two easy ways for you to remember the effects of these receptors and how they work within the body!
Thank you so much!! God bless you !! this video has helped me tremendously ! I was so confused and now I understand the difference!! Please keep posting videos you are great !
Bro most of what you said is incorrect and most is correct, the mnemonic is for beta receptors not the Alpha.
Beta 1 receptor does not cause dilation of anything, like he said (or vasoconstriction, for that matter). It causes renin to be released from the juxtaglomerular cells in the kidneys, which increases BP and contractibility. Beta 2, on the other hand, DOES cause dilation, both in the bronchioles AND the veins, resulting in a lowered BP.
thank you for the clarification! I was confused by this part
B1 causes cardiac stimulation _
Thank you ,very helpful❤️
And alpha 2 can cause dilation
A) Half of what you said is wrong.
B) Can't believe this many people liked and thanked you for it.
Ps. Anybody want to explain how beta blockers effect hypertension using this crayon logic?
How do beta blockers slow heart rate senior crayon?
1000000% Literally half this shit is wrong and exactly why NP's are so sus
Just sat through a whole lecture not understanding this. And now I got it in 5 minutes. Thanks for posting this.
Man, I tried 3 years to remember it and I could never do it. You just saved my life in 5 minutes.
Lol bruh
First semester Nursing student here...... I was almost in tears thinking I would never understand this!!! THANK YOU!!!!
Seriously I spent 4 years in Med school, why did no one explain it this way?? I could never keep these straight, thank you ❤️❤️
Thanks for the help, I was so lost with "memorizing" receptors and was glad I looked up your video to "learn" the difference between Alpha and Beta receptors. Real simple.
OMG I have been sitting here for over an hour trying to figure this stuff out and took me 5 minutes with this video. Thank you.
Oh my goodness! I AM SO GRATEFUL for simplifying this for me. This has helped immensely! THANK YOU
You are a genius. You made everything I've been trying so hard to understand, clique all in 5 minutes. THANK YOU!
My goodness, please continue to make videos like this. This is fantastic. You blew my mind ! Sometimes it just seems so impossible to get and than BAM.....Thank you again
5 minute video that taught me an entire lecture. I now understand what I am studying. Thank you
Thank you for this I'm a nursing school student and I could not wrap my head around this!!! You just made it so much clearer and now I fully understand!! 😁
I watched 20 youtube videos and read 15 articles to no avail. You helped me memorize it in 5 min. Thank you!!
Thank you Dr. Hooks! Fantastic SIMPLE explaination! Loved it! EXCELLENT!!!!
How simple!! I have struggled to remember this for some time. Thank you!
I've been struggling with this for far too long... Thank you so much!
OMG so thankful for the simplicity!!! Will NEVER forget now!!!
Wowww😀I can finally go on remembering these the right way..I can't believe it was this easy and I kept confusing them all the time..thank you!!!
Hey Buddy, You are amazing! The first method you showed totally made sense to me! Such an easy way to get it ! You made my day. Cheers!
just a little correction, or perhaps, to make it more accurate.
alpha 1 receptors is present in smooth muscle, and is targeted by meds to block them, to cause vasodilation...the heart does NOT get dilated, as i believe such a medicament would get pulled from the market pretty quickly!
The "1 heart, 2 lungs" mnemonic is for the Beta-receptors, not for alpha receptor as you mention. B1 in heart, B2 in lungs.
alpha 1 - smooth muscle/vessels
alpha 2 - in CNS, post-synaptic receptors, agonism of which will block the sympatetic tone, and cause vasodilation.
Thank you!! I was about to comment about how this was inaccurate, but you summed it up 10x better than I would've. I'm worried about all these med students in the comments saying, "thank you so much! I finally understand this!" 😳
Also, I was under the impression that α2 receptors also cause vasoconstriction, since α2 antagonists cause vasodilation. Is that wrong?
@@MeanBeanComedy Yes, it is. I am reading from my pharma book, alpha 2 blocks sympatethic tone (not 100% sure of mechanism, but i do believe alpha 2 inhibits alpha 1) either way. stimulating Alpha 2, enhances blockage of sympatethic tone, which yields vasodilation 😊 Alpha 2 agonist is used in hypertension.
@@skarpengland Then why does yohimbine cause vasodilation? It was used as an ED med for a bit, remember!
Alpha 2 should inhibit some aspects of 1 and enhance others.
Oh man. So straight forward and simple. Thank you!!!
Wow! This is both the best explanation and memory device. Thank you!!
Great video! This video truly helped my wife understand these receptors. Thank-you!
Excellent video... It's extremely simple and helps in retaining the basics- thank you!!!
Thank you so, so much! So useful! I know about 1 heart/ 2 lungs but not about constrict/dilate! Life saver! 😻
beta 1 receptor causes cardiac stimulation.. not dilatation..
Exactly
I am 100% sure that this is what he meant. Good catch tho.
@@thatmd If that's what he meant then the whole diagram is wrong.
@@j.j.bichard9123 Any source?
@@j.j.bichard9123 No, I am 100% sure she means a semantic relationship between the two (or be it the mere "fact" as a silent implication), which he supposedly was 100% aware of.
BEST TUTORIAL! Made it super easy! Thank you!
