- Mediated by the sympathetic system except from in sweat and salivary glands (parasympathetic)
- Alpha1 receptors: vasoconstriction
- Inositol triphosphate (IP3) is a second messenger increased by alpha adrenoceptors. Binds to the ER and increases calcium concentrations leading to smooth muscle contraction,…
