PATHOLOGY

Detailed explanation-1: -The sympathetic nervous system activates the sweat glands through the chemical messenger acetylcholine. People with hyperhidrosis produce several times more sweat than normal because they are particularly sensitive to this signal. Hyperhidrosis seems to run in families, but we don’t know much more about what causes it.

Detailed explanation-2: -Your sympathetic nervous system is a network of nerves that helps your body activate its “fight-or-flight” response. This system’s activity increases when you’re stressed, in danger or physically active.

Detailed explanation-3: -The autonomic nervous system controls all “automatic” body functions, such as breathing, heart rate, blood pressure, sweating, mouth-watering (salivating), and the movement of food through the intestines (peristalsis).
