Sensory receptors send information to nerve endings deep in the skin. That information is then sent to the spinal cord and brain. What is one way that this process protects us?

Sensory receptors detect potentially harmful stimuli and send signals through nerves to the spinal cord and brain. The brain can interpret those signals as pain, warning us to stop or change what we are doing before we cause more damage. For example, pain can alert someone that they are performing an exercise incorrectly. So the correct choice is “It enables us to register pain when something we are doing could cause damage.”
