Which of the following nerves causes the adrenal medulla to release epinephrine and norepinephrine and also speed up body activities?
The parasympathetic nervous system is the segment of the autonomous nervous system, that assists with normal autonomic functions. In other words, you are normally in parasympathetic nervous system control for most of your existence. However, under emergency and stressful situations, the body begins to change in order to prepare you for the pending circumstances. This is known as the sympathetic nervous system. Norepinephrine and epinephrine are two hormones that are released in response to emergencies within the body. These two hormones often lead to what is commonly called an 'adrenaline rush,' which is the feeling of urgency that comes during stressful situations. Norepinephrine and epinephrine help the body to perform at optimal levels during such events.
