What is the role of muscles in maintaining posture?
Muscles contract to keep the body upright and stable
Describe what happens during rotation of a joint
A bone turns around its axis
What might happen to movement if a joint is injured?
Movement becomes limited or painful
Why are tendons important for movement?
They transmit force from muscles to bones
What type of bones are found in the wrist and ankle, and what is their main function?
Short bones - provide stability with limited movement
Explain what happens inside a muscle when it contracts
Muscle fibers shorten to pull on bones and create movement
Compare hinge joints and ball-and-socket joints
Hinge joints move in one direction, ball-and-socket joints move in many directions
Explain why warming up before exercise helps prevent injury
It prepares muscles and joints reducing the risk of strains and sprains
Explain how a joint, muscle, and bone work together when you lift your arm
Muscles contract, tendons pull bones, and joints allow movement
