Beta-1 receptors are found in the heart, and when stimulated will increase herat rate and cardiac contractility. Beta-2 receptors are found on vascular smooth muscle located in the heart and skeletal muscle, and when they are activated, they dilate and decrease SVR.
1 Muscarinic receptors respond more slowly than nicotinic receptors. 2  The effects of muscarinic receptors may be excitatory or inhibitory. 3  Muscarinic receptors do not affect skeletal muscles, but do influence the exocrine glands as well as the inherent activity of smooth muscles and the cardiac conduction system.uscarinic, G-Protein Mediated Receptors. The key response differences between muscarinic and nicotinic receptors is that the response of muscarinic receptors: (Hoffman and Taylor 2001). 1  Is slower. 2  May be excitatory or inhibitory.
