4 main receptor types alpha 1, alpha 2, beta 1, beta 2, and recently a beta 3 has been identified
Alpha 1 receptors are mostly associated with excitation or stimulation
Alpha 2 receptors are mostly associated with relaxation and inhibition of epi
Beta 1 receptors are found mostly in the heart brain, kidney, lipocytes
Beta 2 receptors are located in the smooth muscle of the eye, arterioles, venules, bronchioles, liver, pancreas, GI and GU tracts
