List the steps of how tissues help your hand move when you touch a hot stove. Nerves in your hand send a message to
the spinal cord. A reflex takes place when nerves in the spinal cord send signals to muscles in your hand that cause you to move it off the stove. Then, the nerves send a message up the spinal cord, where the brain receives it.
