This resource appears to be designed to build towards this crosscutting concept, though the resource developer has not explicitly stated so.
Comments about Including the Crosscutting Concept
Teachers should emphasize the connections to the Crosscutting Concept by focusing on the components of the nervous system and musculoskeletal system, and on the interactions between them. Students may require some background and/or review of these systems in order to understand how perceiving information is the domain of the nervous system and responding to that information requires the musculoskeletal system. It would also be helpful to provide the context that these systems also have their own subsystems, as well as being part of the larger human body system.
