Involuntary reflexes are very fast, traveling in milliseconds.
The nerve impulses in the neurons that control these reflexes travel an express route. Our conscious muscular response to a stimulus takes a much longer route. See just how fast your brain and nerves respond to stimuli in this experiment. Ask your partner to release the meter stick without warning. Catch the stick as quickly as you can between your thumb and fingers.
