A short segment on neural communication. A nerve cell is like a tree with a filament-like trunk, and branches on either end. Messages go to receptors on dendrites (the initial branches). Second messengers transfer information through to the nerve cell body, which computes whether to send it on through the neural axon. Sequential interchange of sodium and potassium ions creates an electrical potential down the axon to the terminal branches. Here calcium smashes vesicles filled with neurotransmitter against the terminal branch membrane, spilling neurotransmitter into the synapse. Neurotransmitter stimulates receptors on one or many other nerve cells. Reuptake transporters take neurotransmitter back up into the sending neuron and so mediate the time in which the neurotransmitter is available to send messages.
