Question

Quizplus · Accepted Answer

Efferent neurons carry messages away from the central nervous system (spinal cord or brain) to the peripheral nervous system (muscles or glands), while afferent neurons carry messages from the peripheral nervous system to the central nervous system. Therefore, option A is the correct answer. Association neurons, also known as interneurons, are responsible for connecting afferent neurons to efferent neurons within the central nervous system. Primary neurons are not a recognized classification of neurons.
