Answer 1

D.  nervous, muscular, and skeletal systems

Clarify Question
What is the key concept addressed by the question?
        · This question is asking about the integration of body systems.
What type of thinking is required?
        · Apply level:
            o You are being asked to take what you already know and use, or apply, it the systems that work together to cause movement.

Gather Content
What do you already know about movement? What other information is related to the question?
        · To move, a plan must be formulated in the central nervous system.
        · Once the plan is formulated, the message must be passed along through nerves to the muscles.
        · The move is accomplished by the contractions of muscles, which move the bones of the limbs or trunk.

Choose Answer
Given what you now know, what information is most likely to produce the correct answer?
        · While the integumentary, endocrine, and circulatory systems support the health of the body, they do not play a direct role in movement.
        · The actions that are required to successfully complete a movement are planned in the brain, and are carried by the nerves to the muscles, which move components of the skeletal system.

Reflect on Process
Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
        · Apply level:
            o Answering this question correctly depended on your ability to use movement in a new situation. If you got an incorrect answer, did you remember that movement is planned in the central nervous system, or that the muscles contract to move the skeletal system? Did you have trouble extending movement to determine the correct answer?
