 Muscular System Unit Assessment Do Not Write on Test Stephens/Salter/Uchime 2017 Standard: SAP2. Students will analyze the interdependence of the integumentary, skeletal, and muscular systems as
these relate to the protection, support and movement of the human body.
b. Explain how the skeletal structures provide support and protection for tissues, and function together with the muscular
system to make movements possible.
