Autonomics Flashcards
M1R
Salivatory Glands-increase secretion
Acid Secreting Cells of Stomach-increase secretion
M3R
Smooth Muscle Cells Contract
Exocrine glands-Secrete
—SWEAT
M2R
Cardiac
-slow HR
—Decrease cAMP; Gi receptor
Alpha-1-Receptor
Gq=increase Ca++
- constrict smooth muscle of vessels
- liver=make new glucose
- lipolysis
- decrease lacrimal glands
- relax radial muscle of iris-DILATE pupil
Alpha-2-R
Gi=decrease cAMP
- constrict GI (decrease gut motility)
- increase glucagon (pancreas)
- dilate smooth muscle of blood vessels-from decreased cAMP
- increase clotting (platelets)
Beta-1-adrenergic receptor
Gs-increase cAMP
-cardiac tissue
—increase HR and strength of contraction
- dry mouth of salivary glands
- lipolysis
Beta2-adrenergic receptor
Gs-increase cAMP
-bronchiole relaxation (dilation)
-GI smooth muscle relax (decrease gut motility)
-vascular smooth muscle relax
-increase glycogenolysis
-relax ciliary muscle
—flatten lens so you aren’t locked in; aware of surroundings
Beta3-adrenergic receptor
Gs-increase cAMP
Lipolysis-white adipose
Heat production-brown adipose
