Alpha & Beta Receptors

An important aspect of pharmacology class is learning about alpha & beta receptors and what occurs when they are agonized. This will make understanding the CNS, PNS and some of the medications an overall easier process.

Look below for what occurs when certain receptors are agonized.
                                                                 ⬇️ 

Alpha 1 - Vasoconstriction 

Alpha 2 - Glucagon secretion
Insulin restriction
Norepinephrine release

Beta 1 - ⬆️ Heart rate 
⬆️ Contractility 
⬆️ Conduction 
Urinary retention due to secretion of renin 

Beta 2 - Bronchodilation  
Vasodilation 
Insulation secretion
Uterine relaxation
