Aspirin is a pharmaceutical drug often used to treat pain, fever, and inflammation. A drug is any substance (other than food that provides nutritional support) that, when inhaled, injected, smoked, consumed, absorbed via a patch on the skin, or dissolved under the tongue causes a physiological change in the body.
In a crisis, the sympathetic division of your autonomic nervous system (ANS) mobilizes your body for action, directing your adrenal glands to release the stress hormone epinephrine (adrenaline) and norepinephrine (noradrenaline). To provide energy, your liver pours extra sugar into your bloodstream.
The sympathetic nervous system is described as being complementary to the parasympathetic nervous system which stimulates the body to rest-and-digest or feed and breed.he autonomic nervous system functions to regulate the body's unconscious actions. The sympathetic nervous system's primary process is to stimulate the body's fight-or-flight response.
