Integumentary and endocrine systems Muscular and respiratory systems Nervous and muscular systems Skeletal and nervous systems
I gave my students this multiple choice question: A cook touches a hot stove and quickly moves his hand away. What are the two primary body systems that work together to produce this response?

Only one answer is correct among these 4 choices:
- Integumentary and endocrine systems
- Muscular and respiratory systems
- Nervous and muscular systems
- Skeletal and nervous systems

Could you tell me which one is correct?

Nervous and muscular systems
