Name all of the adrenergic receptors:
|
beta 1
beta 2 alpha 1 alpha 2 |
|
|
Stimulation of beta 1 receptors:
|
-Heart: increase HR, force of contraction, automaticity
-Kidney: increase renin release |
|
|
Stimulation of beta 2 receptors:
|
-Bronchioles: bronchodilation
-Pregnant uterus: relaxation (stops pre-term labor) -Blood vessels: vasodilation (increases blood to the heart, brain, and skeletal muscles) |
|
|
Stimulation of alpha 1 receptors:
|
-Blood vessels: vasoconstriction (increases BP, decongestant effect)
-Intestinal smooth muscle: relaxation -Pregnant uterus: uterine contraction -Liver: glycogenolysis, gluconeogenesis (increases blood glucose) |
|
|
Stimulation of alpha 2 receptors:
|
-Pancreatic beta cells: inhibit insulin secretion
-Vascular smooth muscle: vasoconstriction -Nerve endings: inhibit release of norepi. (does not produce sympathetic response) |
