Sensory neurons
... A Motor Neuron is a specialised nerve cell that has the main purpose to carry a message from the CNS to a muscle cell. Motor Neurons send short pulses which produce a twitch in the body, if these twitches become so fast, they produce smooth movement of the body which is known as Tetanus. Motor Neuro ...
