The neuron is a particular cell that has the ability to process and transmit information through either chemical or electrical signals. Neurons can be found throughout the animal kingdom, from small roundworms containing around 300 nerves in their entire nervous system, to humans with over eighty six billion neurons. In the human body, nerves can be found in the central nervous system (CNS) which consists of the brain and the spinal cord, which then attaches to the peripheral system, a system which
