Soma: cell body, dendrites channel info to here and it builds up as an electro-chemical signal. Axon: a long tail that leads away from the soma and toward the next neuron: covered by a myelin sheath: a layer of fatty cells that allow the signal to travel very rapidly from neuron to neuron. When it reaches the end of the axon, neurotransmitters are released: chemical signals that ravel from one neuron to another. Central nervous system: looking at the brain as a whole: brain stem. At the top of the spine and bottom of brain.
