What does reaction time measure?

What happens in your body during a reflex?
Nerves sense danger → spinal cord sends signal → muscles move.
Describe how the nervous, muscular, and skeletal systems work together to perform a movement like kicking a ball.
The brain sends a message through nerves → muscles contract → bones move at the joint
