Detailed explanation-1: -The sympathetic nervous system releases norepinephrine (NE) while the parasympathetic nervous system releases acetylcholine (ACh). Sympathetic stimulation increases heart rate and myocardial contractility.

Detailed explanation-2: -Your autonomic nervous system, which is a part of your peripheral nervous system, helps your brain control all of the vital organs in your body. That also helps your brain care for itself. An example of this is your brain controlling your heartbeat, which ensures your heart pumps blood to your body and brain.

Detailed explanation-3: -This can include control of your heart rate, blood pressure, digestion, urination and sweating, among other functions. The parasympathetic part of your autonomic nervous system balances your sympathetic nervous system.
