Movement of our limbs, jaws, tongue, etc, require muscular movement. The contractile property of muscles are effectively used for locomotion and other movements by human beings and majority of multicellular organisms. Locomotion requires a perfect coordinated activity of muscular, skeletal and neural systems. In this chapter, you will learn about the types of muscles, their structure, mechanism of their contraction and important aspects of the skeletal system.
Assertion (A): Locomotion is a complex physiological process. Reason (R): Locomotion requires perfect coordinated activity of muscular, skeletal and neural systems.
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
NCERT confirms locomotion is complex (Assertion true). NCERT states “Locomotion requires a perfect coordinated activity of muscular, skeletal and neural systems” (Reason true). The Reason explains WHY locomotion is complex - it requires perfect coordination of three different body systems working together, explaining the basis for its complexity.
