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!

Catecholamines Stimulus- Acute stress Target organs- Liver, heart, adipose, blood vessels, lungs, GIT Actions- Increase glucose level, increase BP

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.

Chrommafin cells in adrenal medulla have lost axons and dendrites.They are only post ganglionic cell bodies.

[@dzastro8908]

Exactly 👌🏼

[@vinavaldez3024]

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😊

[@radi00_]

What do you do ? Do you read books related to medicine to get information or you are a medical student? No offense I'm just curious!

[@marwamakki2699]

I have no idea what have i done without ur videoss fr

[@rinc2006]

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)

[@Enrique22n]

abdul rahman you are correct.

[@Ahmashpapi]

correct its the Beta2 receptor

Sometimes, thinking, visual picture and hearing can also stimulate hypothalamus to send down action potentials and stimulate thoracolumbar outflow.

[@aadilhussain3401]

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

[@muhammadrafaythaheem9731]

NinjaSir: You don't wanna pee on the orangutan Darn it! My plans! 🤣🤣🤣

[@abdurahimmudi8260]

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.

[@2YKSS2N]

thank you for sticking through the whole process of making this video

[@dr_ismail_wazir]

you made is so clear for me, cant express how thankful im .

[@Tutu.i]

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

[@alaak2192]

What a simplification in a professional form? Wow really amazing,Go on !

[@kemiyoshida]

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).

[@NinjaNerdOfficial]

+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.

Sir please stand at side when u had finished lecture to take screen shot for revision

[@Turagrong]

I never got why everybody is speaking about BP when it is perfusion that matters... The blood is indeed redistributed during acute stress reaction, but how overall increase in resistance helps to increase perfusion? Is it because of increased velocity of blood - that the blood doesn´t spend time in larger vessels and goes more quickly from the heart to tissues and backwards?

NT that release to stimulate Chrommafin cell is Acetylcholine not NE right? If it’s like that, so before it stimulates chrommafin cell, does NE participate in the journey as the NT or not?

Manh where is hyper and hypo secretions of adrenal gland lecture Plz plz do upload tht video soon 🙏🏿🙏🏿 And thanks for making such great videos ☺️

[@naylar.aprilla4416]

Thank you very much for the really great video! I would like to ask about the part at 23:10 where you mentioned that our blood vessels to the kidney and tissue constrict in order to inhibit their activities. But in 21:21, vasoconstriction causes the blood pressure to increase. So in that case, isn't constricting the blood vessels to the kidney and skin actually increasing the blood pressure thus leading to increased activity of those organs? That means more blood supply are going to the kidney and skin right?

[@yarenkandaz1989]

the activity of kidney is more related to how much blood is going there because of hidrostatic pressure that causes filtrat to develop. actually pressure of blood isn’t that significant

[@sumeethkumar1443]

More volume more filtrate so on vasoconstriction blood volume decreases,filtrate decreases,urine output decreases

[@J3ug]

why dont you name the receptors ???!!
