GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -Often called the emotional brain, the amygdala pings the hypothalamus in times of stress. The hypothalamus then relays the alert to the sympathetic nervous system and the signal continues on to the adrenal glands, which then produce epinephrine, better known as adrenaline.

Detailed explanation-3: -The sympathetic nervous system promotes the fight-or-flight response while the parasympathetic nervous system helps calm the body once the threat is gone.

Detailed explanation-4: -Epinephrine is part of your sympathetic nervous system, which is part of your body’s emergency response system to danger-the “fight-or-flight” response. Medically, the flight-or-flight response is known as the acute stress response. Epinephrine is also called a catecholamine, as are norepinephrine and dopamine.

Detailed explanation-5: -The parasympathetic part of your autonomic nervous system balances your sympathetic nervous system. While your sympathetic nervous system controls your body’s “fight or flight” response, your parasympathetic nervous system helps to control your body’s response during times of rest.
