Question

Quizplus · Accepted Answer

Motor neurons are responsible for transmitting signals from the central nervous system to the muscles or glands, resulting in specific movements or actions. In this case, Chandra's body reacted to the unpleasant smell by wrinkling her nose and grimacing, which required the activation of specific facial muscles through the motor neurons. The sensory neurons are responsible for transmitting sensory information from the environment to the central nervous system, while the interneurons facilitate communication between different neurons in the central nervous system. Glial cells provide support and protection to neurons but do not participate in transmitting signals related to movements or actions.
