Motor control is initiated by lower motor neurons and transmitted to upper motor neurons by interneurons situated within the CNS.

Question

Quizplus · Accepted Answer

Motor control is initiated by upper motor neurons in the brain, which then transmit signals to lower motor neurons in the spinal cord or brainstem; these lower motor neurons directly control muscles. Interneurons within the CNS can modulate this pathway, but the initiation and primary transmission of motor commands follow a top-down approach from upper to lower motor neurons.
