                   ly charged mol e cu les both inside and out side every nerve
                   cell, set up a dif fer ence of elec tri cal char ges along the
                   length of the cell mem brane. To send a stim u lus, human
                   neu rons require an aver age elec tri cal charge of minus 50

                   mil li volts (One mil li volt is 1 thou sandth of a volt). At
                   this point, the nerve sig nal is trans mit ted by the axon.
                   After every nerve sig nal pass es, potas si um ions flow
                   from the cell mem brane. After every sig nal, the neu ron
                   must be recharged. In order to do that, it takes ions back
                   until the poten tial level is regained.
                       For a neu ron to send a sig nal takes around 1 thou -
                   sandth of a sec ond, so in one sec ond, it is pos si ble to send
                   at most 1,000 sig nals. In gen er al, how e ver, only 300 to 400
                   sig nals take place every sec ond. Human nerve cells are of

                   place at speeds between 3 and 100 meters (9.8 and 328

                      Axon




               Electrical current accumulated on a myelin sheathed axon ganglion continues on
               by moving from one to the next. Signals are thus transmitted along the nerve
               cells. Every detail of this system has been specially created for you to perceive
               the outside world and react as necessary, and to establish coordination with the
               brain for your body to perform all its vital functions.
