Beta and Alpha Adrenergic Receptors

this receptor acts in smooth muscle glands and has greater sensitivity to NE than EPI

activates phospholipase C which increases Ca2+

excitatory

this receptor is presynaptic and has a greater sensitivity to NE than EPI

decreases adenylate cyclase activity which decreases cAMP

excitatory and inhibitory

this receptors acts in hear muscle and kidney, the sensitivity for NE and EPI is equal

increases adenylate cyclase activity which increases cAMP

excitatory

this receptor acts in blood vessels and smooth muscles, the sensitivity to EPI is greater than NE

increased adenylate cyclase activity which increases cAMP

inhibitory

This receptor when stimulated will cause

contraction (vasoconstrict) ateriole smooth muscles 
contraction (vasoconstrict) veins (smooth muscle)
secretion from salivary glands 
contraction of pilomotor muscles

This receptor when stimulated will cause:

excitatory response in heart cells
renin secretion in kidney

This receptor when stimulated will cause:

relaxation (vasodilation) vessels of skeletal muscles
relaxation (dilation) of bronchiole smooth muscle 
relaxation of the uterus
relaxation of bladder smooth muscle
