Term: Sympathetic Nervous System
Definition (Myers): the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations1
Definition (alternative): a branch of the autonomic nervous system along with the enteric nervous system and parasympathetic nervous system2
Contextual explanation: The sympathetic nervous system is the part of the autonomic nervous system. The autonomic nervous system controls the fight-or-flight response. The sympathetic nervous system kicks in when your body is aroused (think of it more like excited or tense). Think about the time you were about to take a test when your hands were sweaty, or were hiding or lying to someone and your heart was beating at 10000 miles per hour. That was your sympathetic nervous system.
