brane. Every neu ron resem bles a min i a tured bio log i cal
bat tery ready to dis charge its ener gy. The ions, elec tri cal -
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
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
51
dif fer ent lengths. The trans mis sion between cells takes
place at speeds between 3 and 100 meters (9.8 and 328
feet) per sec ond. 52
Signals moving my

transmission.
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.
