Question

Quizplus · Accepted Answer

Motor neurons carry messages from the central nervous system to muscles, causing them to contract and move. Sensory neurons carry information from the body's sensory receptors to the central nervous system, while the sympathetic nervous system is a part of the autonomic nervous system that mobilizes the body in response to stress or danger. The hypothalamus is a small structure in the brain that plays a role in regulating various bodily functions, but it does not directly carry messages to muscles.
