DOK Level 1: Recall

Explain how the muscular system and skeletal system work together to facilitate movement.

• The muscular system provides the force needed for movement, while the skeletal system provides the structure and support.

• The skeletal system generates force, and the muscular system provides the structure.

• The muscular system and skeletal system do not interact.

• The skeletal system controls the muscles directly.

DOK Level 1: Recall

Explain how the nervous system and muscular system interact to produce a reflex action.

• The nervous system sends a signal to the muscles to contract in response to a stimulus.

• The muscles send a signal to the nervous system to initiate a reflex.

• The nervous system and muscular system do not interact during a reflex.

• The reflex action is controlled solely by the muscular system.
