The sympathetic nervous system is responsible for the body's "fight or flight" response, which includes the release of adrenaline and increased heart rate, as seen in Joe's situation. The central nervous system includes the brain and spinal cord, but does not specifically control this response. The parasympathetic nervous system is responsible for the body's "rest and digest" response, and the somatic nervous system controls voluntary movements of the muscles.
