In response to a harmful stimulus, initiate neural impulses leading to the sensation of pain. a. ganglion fibers b. feature detectors c. nociceptors d. bipolar cells

In response to harmful stimulus, nociceptors initiate neural impulses leading to sensation of pain. Nociceptors are receptors located at the end of a sensory neuron's axon. They respond to potentially damaging things by sending a signal to the spinal cord and brain that lets it know that there is a possible thread. If the brain believes the threat is real it will create a painful sensation at the body part in danger to alert the body and save itself from the threat.
