<P> These neurons connect the brain to the appropriate level in the spinal cord , from which point nerve signals continue to the muscles by means of the lower motor neurons . The neurotransmitter glutamate transmits the nerve impulses from upper to lower motor neurons , where it is detected by glutamatergic receptors . </P>
