Question

Quizplus · Accepted Answer

The sympathetic nervous system dominates in fight-or-flight situations, where the body prepares for heightened physical activity and increased arousal. It is not always excitatory, as it can also inhibit some functions like digestion. It does not innervate only tissues concerned with protecting the body against challenges from the outside environment, as it innervates a wide variety of tissues and organs in the body. Finally, it is not part of the somatic nervous system, which controls voluntary movements.
