Which nerve fibers synapse on the alpha motor neuron in the spinal cord?
Both the corticospinal tract and afferent Ia sensory nerves regulate the alpha motor neuron by snapping on it in the anterior horn of the spinal cord.
Renshaw cells are interneurons that are stimulated by the alpha motor neuron and then, by a feedback mechanism, inhibit the alpha motor neuron, causing autoinhibition.
