Quizplus · Accepted Answer

The sympathetic nervous system is one of the two main parts of the autonomic nervous system and is responsible for speeding up body functions in response to stress or danger. Its opposite, the parasympathetic nervous system, slows down body functions. The sympathetic nervous system does send messages to and from the brain, but it does not control thought and intelligence.
