Alpha-2 receptors are located both presynaptically and post-synaptically.

This doesn't make sense. Alpha 1 receptors in the kidney inhibit renin release, the same renin that is a part of the RAA system, one of the most powerful VASOCONSTRICTIVE mechanisms our body has, and yet Alpha 1 stimulation causes overall vasoconstriction? That would mean our body is ineffeciently working against itself, something I have yet to see. And this is separate from the negative feedback mechanism.

Prashanth Raju (5 месяцев назад)
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

5:15 why renin inhibited by alpha 1 receptor?

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?

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!
Sadie Michael (1 месяц назад)
Catecholamines are hormones produced by the adrenal glands, which sit on top of the kidneys. Dopamine, epinephrine (adrenaline), and norepinephrine are the main catecholamines.

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?

Ammar Ahmed (1 год назад)
Your really appreciate your struggle .......if I am wrong please correct my mistake .....
Ammar Ahmed (1 год 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.....
Δάφνη Κόλλια (4 месяца назад)
it says inhibition of renin release..
Tuyambeka Hashipala (7 месяцев назад)
Ammar Ahmed you are right. ..a1 results into decreased renin secretion

isn't the nictontic receptors only found in cholinergic neuron? in 3:14 minute
Prashanth Raju (5 месяцев 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 (1 год 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." J Allergy Clin Immunol. 2002 Dec;110(6 Suppl):S313-7

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...
