Dr. Wang Jianlong
Epinephrine causes a decrease in the tone of the small intestinal smooth muscle and also reduces its excitability. Normally, small intestinal smooth muscle contains two types of receptors: alpha and beta receptors. Stimulation of alpha receptors leads to reduced local muscle tone and excitability. In daily life, effectively managing emotions can help reduce the body's secretion of epinephrine.
