Sympathetic receptors

   alpha 1 receptors --------    q

---increase vascular smooth muscle contraction

---increase papillary dilator muscle contraction --- mydriasis

---increase Intestinal & Bladder sphincter muscle contraction

 alpha 2 receptors  ---------    i

-----decrease sympathetic outflow

-----decrease Insulin release

 beta 1 receptors   -----------   s

--- increase HR

--- increase contractility

--- increase renin release

--- increase Lipolysis

 beta 2 receptors ------------   s

-- increase HR

-- increase Contractility

-- increase Lipolysis

-- increase Insulin release

-- decrease Uterine tone

-- vasodilation

-- bronchodilation
