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.
SA type 1 receptors are associated with myelinated fibers greater than 10 m in diameter which terminate in Golgi-type organs. They are located in the joint ligaments and respond both to joint position and movement. SA type 2 receptors terminate in Ruffini-type endings and are associated with type A beta fibers.
