Adrenergic receptors
those that normally (only) respond to NE release in the body.
Adrenergic receptors
alpha
b1
b2
Alpha adrenergic receptors
contracts smooth muscle

adrenergic
Beta 1 adrenergic receptors
adrenergic

stimulates heart rate, strength

always in heart
Beta 2 adrenergic receptors
adrenergic

relaxes smooth muscle

increase metabolic rate
Cholinergic receptors
those that normally respond to acetylcholine release in the body.
Cholinergic receptors
muscarinic
nicotinic
Muscarinic cholinergic receptors
chiefly at effector after postganglionic neuron

1. contracts smooth muscle (EXCEPT GI and urinary sphincters, and Blood vessels) The eye sphincter muscle contracts causing the pupil to constrict.

2. Stimulates exocrine glands

3. decreases heart rate and sometimes contractility.
effector

post-

sphincters

glands

decreases
Muscarinic cholinergic receptors (chiefly at ________ after ____ganglionic neuron)

1. contracts smooth muscle (EXCEPT GI and urinary _________, and Blood vessels) The eye sphincter muscle contracts causing the pupil to constrict.

2. Stimulates exocrine ______

3. _________ heart rate and sometimes contractility.
dilated
Peripheral blood vessels are _______ with muscarinic drugs.
Nicotinic cholinergic receptors
(at ganglia, neuromuscular junctions, and adrenal medulla)

1. may stimulate both the sympathetic and the parasympathetic system simultaneously (stimulates both sympathetic and parasympathetic ganglia)

2. stimulates adrenal medulla (sympathetic-like effect)

3. stimulate skeletal muscle (neuromuscular junction) - voluntary system
simultaneously
