Neuron is a cell of the nervous system that is involved in carrying of impulses between the nervous system and the rest of the body. There are three types of neurons namely; relay neuron, motor neuron and the sensory neuron. Neuron is made up of various parts that enhance is activity in transmission of impulses/information which includes, dendrites, cell body, axon, myelin sheath among others. The conduction of information in the neuron starts from the Dendrites, then to the cell body, to axon and then to synapse where a neuron links with another and the process is repeated. Therefore; the correct answer is C
