Question

Is the reaction of 'fight of flight' due to the action of the parasympathetic nervous system or the sympathetic?

Answer 1

Sympathetic nervous system. Thesympathetic nervous system originates in the spinal cord and its main function is to activate the physiological changes that occur during the fight-or-flight response. This component of the autonomic nervous system utilises and activates the release of norepinephrine in the reaction.
