A Neuron


A neuron is an individual nerve cell. A stimulus begins from the branches of dendrites until it reaches the cell body.The impulse then travels from the cell nucleus along the Axon to the terminal end where it jumps from one neuron to the other. The space where the nerve impulse jumps from one neuron to the other is called the synapse. The transfer of impulses depend on the release of chemicals called neurotransmitter. Some neurotransmitters are Acetylcholine, epinephrine, dopamine, serotonin.
