Little detail at the end; I believe it’s Beta 2 adrenergic receptors associated with dilation of the bronchioles! Not Alpha 2! Thanks to your video on adrenergic receptors, in your neurology playlist, I was able to learn about these receptors! Thank you for all of your amazing videos!
Ninja I really like your passion talking and teaching about this stuff.. you had me at cortisol.. but when you looked at the camera and said "Glycerol.. BEAUTIFUL" lmao.. I really enjoyed your lecture.. I learned a lot and am a new subscriber.
omg!omg!omg!... this is soo good.... i know medicine is beautiful... connecting everything is way beautiful.... and the way you doo it , just amazing!...u r teaching us taking the body as a whole..... thank soo much for these wonderful videos!!!
Hello there! You are awesome! When I tried to read the books about this topic, I can’t understand the concept. Just by watching his lecture, I was able to say ‘that’s easy to understand’! Now every time I have to read some medical information topic, I have to watch his lectures first then read the book. It makes my life easier😊
I've always avoided your videos because they were super long and i have little time but wow, you answered all the questions i had on this particular topic.Thank you
i am a ninja nerd addict.however if i am not wrong, i think it is not Alpha2 receptor but the Beta2 receptor that cause broncodilation as against what you have mentioned almost at the end of this video(at 24.50)
I love watching this stuff (and I'm doing so purely out of curiousity, because I have no qualifications in any of this, but the more I watch & read - the more it makes sense) It is "beautiful".
Your way of teaching is extraordinary and very helpful to millions of medical students and professionals all over the world.You may like to correct the last point where you said Alpha-2 in the bronchial smooth muscle to Beta-2.I really admire you and hopefully one day we will meet in person.
Sir chromaffin cells don't have axons they are actually post ganglionic cell bodies, and Beta 2 receptors are present on bronchial smooth muscles not alpha 2
I can't believe I didn't find your channel sooner!!! I actually get it now!!!! Small complaint: Please add subtitles! Seeing the words helps me comprehend better ^-^
This was awesome, thank you. Only note is that the main receptors responsible for vasoconstriction, increase HR and BP are the BETA-1 adrenergic receptors (not alpha-1)... and bronchodilation are BETA-2 Adrenergic receptors (not alpha-2).
+Kayla Akemi As for your comment alpha-1 adrenergic receptor's do play in important role in constricting blood vessels which would cause the increase in peripheral resistance and therefore an increase in blood pressure. Also by constricting certain blood vessels we can divert that blood to the more vital organs. The beta-1 adrenergic receptor's are generally only present on the myocardium of the heart as well as the Juxtaglomerular cells in the kidney this allows for us to increase contractility, heart rate, as well as jumpstart the renin angiotensin aldosterone system. Whereas Beta-2 adrenergic receptor's play a role in vasodilation of blood Vessel's or smooth muscle with in the G.I. tract or respiratory tract, etc. *****Also yes I did make a mistake I should've said beta-2 receptors on the bronchial smooth muscle. That is my mistake*******!!! We plan on making a video focusing more on the sympathetic nervous system and it's receptors within the next week or two.
love ur lecturers always make me laugh at some point 😋mmm love pizza ，cooper cheese， milk ...never mentioned if u love broccoli or any type of veggies😅thnx a lot for all ur amazing lecturers I am addicted to ur channel✌
