If alpha 2 receptor activation leads to decreasing the release of neurotransmitters from the synaptic vessels by negative feedback mechanism. then it ultimately leads to decrease in the sympathetic response right. then how can you say the drugs (Alpha 2 receptor agonist) classified under adrenergic agonist. though they are decreasing the adrenergic or sympathetic response by decreasing the neurotransmitter release

this video has really helped me understand! thank you so much, I was feeling despair over it now I really understand it!

It seems that the alpha 1 receptor and the beta 2 receptor are in direct opposition. How can they oppose each other if they are both are sympathetic responses?

Great job, All your videos are great, only if you can put the slides in the description in youtube, or if you can attach it on fb, so we can download it and print it, that would help us so much, also You should allow people to donate to the channel.

Guys, I’m only 14, so give me a break for asking this. But what is catochlomine?! I have this medical book and it mentions it 100000000 times but never explains what it is or what it does, and I can’t find it in this video. Plz help!

why does alpha 1 receptor inhibits renin release?in fight or flight response, i believe that one's blood pressure would shoot up due to rise in renin release and also vasoconstriction of the vessels, right?

Your really appreciate your struggle .......if I am wrong please correct my mistake .....
Ammar Ahmed (8 месяцев назад)
At interval 5:02 you said that kidney contains a1 receptors which stimulates release of renin but in actual all the tissues to be stimulated have a1 receptors but not heart , JGA in kidney and adipocytes they contain b1 adrenergic receptor ..... b1 receptor in kidney stimulates release of renin not a1.....

isn't the nictontic receptors only found in cholinergic neuron? in 3:14 minute
Prashanth Raju (1 день назад)
no... they found on the both adrenergic & cholinergic post ganglionic neuron. but when it comes to the effector site, it changes. adrenergic neurons have Alpha and beta receptors, while cholinergic neurons have muscarinic receptors

Beta 2 increases glucagon secretion, not insulin
Speed Pharmacology (9 месяцев назад)
"Specific beta(2)-agonist effects on the pancreatic beta cell result in increased insulin secretion, yet other mechanisms, such as increased glucagon secretion and hepatic effects, cause an overall increase in serum glucose and an apparent decrease in insulin sensitivity."

You forgot abt beta 2 receptors that they also r present on liver and cause gluconeogenesis and glycogenolysis thus increasing blood glucose level ... and also cause increase in intracellular potassium intake...

Thank you very much from a second semester, nursing student. I know there are certain classes that people dread (pharmacology, anatomy and physiology, medical terminology, microbiology). But for me, if I can visualize the concepts into some sort of story, I'm golden. Thanks for helping me be able to visualize this.

Thank you for this video. So you are saying that out of the drugs that you presented, Dopamine, NE, and E are catecholamine like and have a short half-life, while the rest like ephedrine, phenylephrine, dobutamine, etc are non-catecholamines and thus has longer duration of action?

Your videos are saving my life for last minute pharmacy revision, one question though, why would inhibiting the RAAS help fight or flight? Wouldn't renin help since it causes vasoconstriction?
Healthy Indulgences Blog (1 год назад)
Why would alpha 1 stimulation cause decreased renin production? How would that be advantageous? It seems as if vasoconstriction would be acting to relieve hypotension, so it would make sense if the other actions of the receptor activation enhanced rather than contradicted this effect. Thanks for the awesome, concise yet informative video!
mattabell10 (1 год назад)
Since alpha 1 agonist action increases SNS response (BP) there is no incentive for renin to be produced, thus the RASS system is not activated. It's the same as if a person is already hypertensive. Activation of RASS would only exacerbate the hypertension.

karirodriguezzzz (1 год назад)
i am a first year medical student and i realise that in the field of illustration this misgonistic view of men soley being depicted is often an issue to be addressed. this comment is to commend you on your usage of a female figure for the purposes of this video at 0.19s during the introduction. !

@mattabell10 Threatened by someone pointing out the fact that the male body is overwhelmingly depicted as the prototype for the human body. Who's the snowflake?
