The smooth muscle, which is innervated by the sympathetic nervous system, controls the diameter of the blood vessel, and it plays an important role in blood pressure.
Vascular smooth muscle has two types of alpha-adrenoceptors: alpha 1 (Î± 1) and alpha 2 (Î± 2). The Î± 1 -adrenoceptors are the predominant Î±-receptor located on vascular smooth muscle. These receptors are linked to Gq-proteins that activate smooth muscle contraction through the IP3 signal transduction pathway.Depending on the tissue and type of vessel, there are also Î± 2 -adrenoceptors found on the smooth muscle.hese drugs block the effect of sympathetic nerves on blood vessels by binding to alpha-adrenoceptors located on the vascular smooth muscle. Most of these drugs act as competitive antagonists to the binding of norepinephrine that is released by sympathetic nerves synapsing on smooth muscle.
