motor neuron

In neurology, the term motor neuron (or motoneuron) classically applies to neurons located in the central nervous system (or CNS) that project their axons outside the CNS and directly or indirectly control muscles. The motor neuron is often associated with efferent neuron, primary neuron, or alpha motor neurons. Motor neurons are neurons that carry signals from the spinal cord to the muscles to produce movement [Wikipedia].
