Q

Alpha-1-Receptor

A

Gq=increase Ca++

  • constrict smooth muscle of vessels
  • liver=make new glucose
  • lipolysis

Q

Alpha-2-R

A

Gi=decrease cAMP

  • constrict GI (decrease gut motility)
  • increase glucagon (pancreas)
  • dilate smooth muscle of blood vessels-from decreased cAMP
  • increase clotting (platelets)

A

Gs-increase cAMP
-cardiac tissue
—increase HR and strength of contraction

  • dry mouth of salivary glands
  • lipolysis

-vascular smooth muscle relax
-increase glycogenolysis
-relax ciliary muscle
—flatten lens so you aren’t locked in; aware of surroundings
