Detailed explanation-1: -Your sympathetic nervous system is best known for its role in responding to dangerous or stressful situations. In these situations, your sympathetic nervous system activates to speed up your heart rate, deliver more blood to areas of your body that need more oxygen or other responses to help your get out of danger.
Detailed explanation-2: -The sympathetic nervous system (SNS) releases the hormones (catecholamines-epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate.
Detailed explanation-3: -The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.
Detailed explanation-4: -The brain stem is an automatic control center for many such important involuntary actions of the body. And, it is a pathway for impulses travelling back and forth between the body and the rest of the brain.
Detailed explanation-5: -The sympathetic nervous system directs the body’s rapid involuntary response to dangerous or stressful situations. A flash flood of hormones boosts the body’s alertness and heart rate, sending extra blood to the muscles.
