Human Motion

-

Here are 7 key points about human motion:


1. Definition: Human motion refers to the movement of the body or its parts, produced by the coordinated action of muscles and the skeletal system.



2. Types of Motion: It includes linear (straight-line), rotational (around an axis), and general motion (a combination of both).



3. Muscular Control: Muscles contract and relax to create motion, working in pairs — one muscle pulls while the other releases.



4. Skeletal Support: Bones act as levers and joints serve as pivot points, allowing smooth and flexible movement.



5. Nervous System Role: The brain and nerves control motion by sending signals that coordinate muscle actions and balance.



6. Energy Source: Movement requires energy, which comes from food converted into ATP during cellular respiration.



7. Applications: Studying human motion helps in sports science, medicine, robotics, and physiotherapy to improve performance and 

prevent injuries.
