You and a friend are studying psychology at the dining room table when you hear something stirring underneath it. You lean over to investigate, and a rat scurries across the floor. Which nervous system kicks into gear in both you and your friend?

Question

Quizplus · Accepted Answer

The sympathetic nervous system is responsible for activating the body's fight or flight response, which includes increased heart rate, heightened senses, and readiness for action. Seeing a rat scurrying across the floor could trigger this response in both individuals. The afferent nervous system transmits sensory information from the periphery to the central nervous system, but it does not kick into gear in response to a specific external stimulus. The parasympathetic nervous system is responsible for the restful, relaxation response in the body, which is not applicable in this scenario. The central nervous system includes the brain and spinal cord, but it does not directly respond to the presence of a rat in the environment.
