The main function of a motor neuron is to convey output signals to muscles for joint control.This involves 'upper motor neurons' in the brain relaying signals to 'lower motor neurons' in the spinal cord, which in turn relay signals to skeletal muscles for joint control.Lower motor neurons are also involved in sympathetic function, such as blood pressure regulation.his involves 'upper motor neurons' in the brain relaying signals to 'lower motor neurons' in the spinal cord, which in turn relay signals to skeletal muscles for joint control.
