Detailed explanation-1: -Sympathetic Autonomic Nervous System: It is the part of the autonomic nervous system located near the thoracic and lumbar regions in the spinal cord. Its primary function is to stimulate the body’s fight-or-flight response. It does this by regulating the heart rate, rate of respiration, pupillary response and more.
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: -Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines-epinephrine and norepinephrine) to accelerate the heart rate.
Detailed explanation-4: -Stimulation by the sympathetic system nerves results in an increase of heart rate, as occurs during the “fight-or-flight” response.
