Question Answer
Alpha 1 Effect on Major Blood VesselsConstriction, increased peripheral resistance, increased diastolic blood pressure.
Alpha 1 Effect on the EyeContraction of radial muscles (mydriasis).
Alpha 1 Effect on Bladder and GI SphinctersConstriction, decreased outflow.
Alpha 1 Effect on LiverGlycogenolysis causing increased blood glucose (not beta 2).
Alpha 2 Effect on EyeDecreased production of aqueous humor.
Alpha 2 Effect on Spinal CordInhibits pain.
Alpha 2 Effect on Pancreatic IsletsDecreased insulin release leading to increased blood glucose.
Alpha 2 Effect on Presynaptic Nerve TerminalsDecreased neurotransmitter release.
Alpha 2 Effect on CNSInhibits baroreflex causing decrease in blood pressure.
Alpha 2 Effect on Nasal VasculatureConstriction (decongestant effect).
Beta 1 Effect on the HeartIncrease heart rate, contractility, and force leading to increased cardiac output.
Beta 1 Effect on the KidneysIncreased renin secretion leading to increased vasoconstriction.
Beta 1 Effect on the EyeIncreased production of aqueous humor (not beta 2).
Beta 2 Effect on Hepatic and Skeletal Muscle Vascular Smooth MuscleRelaxation leading to increased blood flow to skeletal muscles and liver.
Beta 2 Effect on Pulmonary Smooth MuscleRelaxation leading to increased airflow.
Beta 2 Effect on GI Smooth MuscleRelaxation leading to decreased motility of GI smooth muscle.
Beta 2 Effect on Bladder Detrusor MuscleRelaxation leading to decreased motility of bladder detrusor muscle.
Beta 2 Effect on Pregnant Uterus (Myometrium)Relaxation
Beta 2 Effect on Skeletal MuscleIncreased glycogenolysis, increased K+ ion uptake.
Beta 2 Effect on Mast CellsDecreased degranulation.
Beta 2 Effect on the PancreasIncreased glucagon secretion.
Beta 2 Effect on the LiverGlycogenolysis causing increased blood glucose (not alpha 1).
Beta 2 Effect on the EyeIncreased production of aqueous humor (not beta 1).
Beta 3 Effect on FatIncreased lipolysis (complex process).
