α-Adrenoceptor Location and function Alpha 1 receptors are located on: • all vascular smooth muscle, although densities vary throughout the body • GI & urinary sphincters • dilator muscle of the iris • arrector pili muscle of hair follicles • On central and peripheral nervous system 5 Alpha receptors are further sub-divided into two types: alpha 1 (α1) and alpha 2 (α2). α1 receptors are largely involved in smooth muscle contraction in areas such as the uterus, the ureter, the bronchioles, and the blood vessels of the ciliary body The types of sympathetic or adrenergic receptors are alpha, beta-1 and beta-2. Alpha-receptors are located on the arteries. When the alpha receptor is stimulated by epinephrine or norepinephrine. Alpha-1 receptors bind catecholamines including, both epinephrine and norepinephrine. In instances in which there is hypoperfusion secondary to decreased cardiac output or decreased systemic vasculature resistance, alpha-1 receptors become stimulated. It is worth noting that these compounds are not purely selective for the alpha receptor, and. The main difference between alpha and beta receptors is that alpha receptors stimulate the effector cells whereas beta receptors relax the effector cells. The two main types of alpha receptors are alpha 1 and alpha 2 receptors. On the other hand, the three main types of beta receptors are beta 1, beta 2, and beta 3 receptors

Vascular smooth muscle has two types of alpha-adrenoceptors: alpha 1 (α 1) and alpha 2 (α 2).The α 1-adrenoceptors are the predominant α-receptor located on vascular smooth muscle.These receptors are linked to Gq-proteins that activate smooth muscle contraction through the IP 3 signal transduction pathway and Rho-kinase pathway. Depending on the tissue and type of vessel, there are also α. The alpha receptors are divided into two different kinds as well: alpha 1 and alpha 2. When stimulated, the alpha 1 receptors are largely responsible for: Vasoconstriction: constriction of the. Alpha2 receptors are found on presynaptic nerve terminals and inhibit further release of norepinephrine. Beta1 receptors are on the heart and kidneys and lead to increased inotropy/chronotropy and renin release respectively. Beta2 receptors are located on lungs, bladder, uterus, GI tract, blood vessels and lead to smooth muscle relaxation The alpha-1 (α 1) adrenergic receptor is a G protein-coupled receptor (GPCR) associated with the G q heterotrimeric G-protein.It consists of three highly homologous subtypes, including α 1A-, α 1B-, and α 1D-adrenergic. Catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) signal through the α 1-adrenergic receptor in the central and peripheral nervous systems

The neurotransmitter for sympathetic nervous system is norepinephrine (or also called noradrenaline) that acts on adrenergic receptors of the effector organ (alpha 1, beta 1, beta 2 receptors. Adrenergic α 1 receptors (α 1-adrenoceptors) are members of the adrenergic receptor group of G-protein-coupled receptors that also includes α 2A, α 2B, α 2C, β 1, β 2 and β 3.The adrenergic α 1 receptors are further divided into three subtypes: α 1A, α 1B and α 1D receptors. α 1-adrenoceptors are widely distributed in both the CNS and periphery where they play a major role in.
