Ions Involved in Action Potential Propagation Essay.
Nerve and muscle functions involve electrical conduction. However, nerves and muscle are not like electrical wires. Nerve and muscle cells are poor conductors of classical electrical current flow; such current dies out within a few millimeters. Signal transport (Action Potentials), does travel from one end of a nerve to the other. There is no diminishment of the signal, independent of the length of the cell (unlike a wire), and energy is required in the energy transport process itself. Action potential would go from toe to brain in about 1 sec = 100 m.sec.. The resting membrane potential of a nerve (or any cell) is about -70 "millivolts". The minus means that it's negative on the inside and positive on the outside of the cell. Like a voltage can be measured by placing one electrode of a voltmeter inside a cell and the second electrode outside the cell.
Action potential is defined as, an explosive change in electrical......
