Final answer:
The somatic nervous system uses large nerve fibers to alert that body damage may be occurring.
Step-by-step explanation:
The system that uses large nerve fibers to alert that body damage may be occurring is the somatic nervous system.
The somatic nervous system is responsible for voluntary movements and relays sensory information from the body to the brain.
It includes large nerve fibers that transmit signals quickly, allowing for rapid response to potential damage.
For example, if you accidentally touch a hot object, the somatic nervous system signals your hand to quickly pull away to avoid further injury.
