A motor neuron is a cell of the central nervous system. Motor neurons transmit signals to muscle cells or glands to control their functional output. When these cells are damaged in some way, motor neuron disease can arise. This is characterized by muscle wasting (atrophy) and loss of motor function. Motor Neuron.
