Which type of neuron transmits signals from the central nervous system to muscles or glands?

Explanation:
Motor neurons carry signals from the central nervous system out to muscles or glands. They are the efferent part of the nervous system, transmitting impulses from the brain or spinal cord to effectors so actions like muscle contraction or gland secretion can occur. Sensory neurons do the opposite, sending information from the body toward the CNS. A general term like “neurons” is too broad, and “neurological disorders” are not a neuron type. So the correct choice is motor neurons because they specifically send signals from the CNS to muscles or glands.
