Document Summary
Input (going to receive information: transit, output (sends info to the other neurons) How do they work: signals are transmitted electrically and chemically, long distance signals transmitted electrically, signal between neurons transmitted chemically, each neuron sends signal to many other neurons. Ion: electrical charge, osmosis, voltage (electrical potential, cell membrane. Cells: have cell membrane (layer of fat that surrounds the cell, fat repels the water and anything with an electric charge, ions important for neuronal function. Ions are atoms with an electrical charge: sodium = na. Fred(cid:1685)s door is fred(cid:1685)s door: channels allow specific ions in or out of the cell, whether an ion moves in or out of the cell depends on the forces of the ion, electric force. Ions of the same charge (i. e 2 positives or 2 negative) repel each other. Ions of different charge are attracted to each other.
