Explanation:

To solve this, we analyze each option:

• Glial cells support neurons, not transmit messages to muscles/glands.
• Afferent neurons carry signals to the brain/spinal cord (sensory), not from.
• Schwann cells insulate axons, not transmit messages to effectors.
• Motor neurons (efferent) transmit signals from the brain/spinal cord to muscles or glands (effectors) to initiate responses.

Answer:

D. motor neurons
