Which part of the body is most commonly associated with work-related musculoskeletal disorders?
Answer: Lower back
The lower back is one of the most common areas affected by work-related musculoskeletal disorders due to poor posture and repetitive lifting.
What is the function of tendons in the musculoskeletal system?
Answer: Connect muscles to bones
Tendons connect muscles to bones and transmit the force needed for movement.
What biomechanical principle explains the stress placed on joints during repetitive motion?
Answer: Cumulative trauma
Cumulative trauma refers to repeated stress and strain on joints and tissues over time, leading to injuries.
Which joint type allows for the greatest range of motion?
Answer: Ball-and-socket joint
Ball-and-socket joints like the shoulder and hip allow for the widest range of movement in multiple directions.
Why is neutral posture important in ergonomic design?
Answer: Minimizes strain on the musculoskeletal system
Neutral posture reduces stress on muscles and joints, minimizing the risk of injury during prolonged tasks.
Which muscle group is primarily responsible for maintaining upright posture?
Answer: Core muscles
The core muscles, including the abdominals and spinal extensors, stabilize the spine and support upright posture.
