Question

Quizplus · Accepted Answer

Afferent neurons are sensory neurons that carry signals from the peripheral nervous system to the central nervous system. In the case of the sunburn, afferent neurons in the skin would be responsible for sending messages to the brain reporting the pain from the burn. Motor neurons, on the other hand, carry signals away from the brain and spinal cord to activate muscles, while interaction neurons and efferent neurons are not directly involved in sensing pain.
