Most, but not all organs that are innervated by the sympathetic system are also innervated by the parasympathetic branch.

Sympathetic System

Part of the autonomic nervous system that activates the body's rapid involuntary response to dangerous or stressful situations (fight or flight response).

Parasympathetic Branch

Part of the autonomic nervous system responsible for stimulating "rest-and-digest" or "feed and breed" activities that occur when the body is at rest.
