sympathetic nervous system

Explanation:

The sympathetic nervous system initiates the flight-or-flight response in response to a perceived threat or harmful event.

During this response, the adrenal gland sends out signals to secrete norepinephrine and epinephrine. These hormones have many effects on the body during the fight-or-flight response, including:

  • increase of blood flow to muscles
  • pupil dilation
  • increase in blood pressure
  • increased awareness
  • release of glucose into the blood stream
