Adrenergic Receptors
NE (a1, a2, b1, b2)
Cholinergic
Ach: Nicotinic and Muscarinic
Nicotinic receptor location:
preganglionic for both symp and parasymp
Muscarinic Receptors: neurotransmitter and location
Ach, and postganglionic parasympathetic
Muscarinic agonists will cause:
Miosis (pupilary constriction)
Accomodation
Slow HR
Bronchoconstriction
Increased GI/GU motility
Increased secretion
a1 agonists will cause
Vasoconstriction
Increased TPR
Increased BP
Mydriasis (dilate pupil)
Tightening of sphincters
a2 agonists will
Inhibit further NE release (attenuate sympathetic response?)
B1 cells located at
HEART HEART HEART HEART
B1 agonists will
Increase heart rate
increase heart contractility
increase renin release
B2 located at
Brochial smooth muscle
Blood vessel smooth muscle
Cardiac muscle (a little)
B2 agonist will:
Relax smooth muscle (bronchodilate)
