The Nerves Are Electric
Wires
We
all know that an electrical wire is composed of two parts: the inside contains
generally the copper wire through which the electrical current flows, and the
outside consists of insulating material made of rubber or plastic which serves
to insulate the electric wire preventing a short circuit.
The nerve cell branch has exactly the same composition as an electrical wire: inside there is the nerve fiber which is made up of neurofibrils (very thin fiber or wires) through which the human electrical current flows; outside there is an insulating material called Schwann membrane which also prevents short circuits. If the Schwann membrane is damaged, for example by a virus — as can happen to the rubber sheath of electrical wire either by cracking or burning — the human electricity dissipates along the tissues and the person becomes partially or totally paralyzed.
People that suffer, for example, from multiple sclerosis have a disease which affects the Schwann membrane or the rubber of the nerve. In this condition the nerves which activate walking are shorted. This same electrical current will not reach the specific muscle with the normal intensity, because of the short circuits along the nerve fiber — thus resulting in partial or total paralysis.
Similar to the shell of the chicken egg, all nerve fibers are charged with electricity. They have positive electricity outside and negative electricity inside.
Something curious happens when the nerve is touched or stimulated. (Diagram) Instantaneously an electrical transposition takes place. The positive electricity moves inside of the nerve fiber and the negative electricity moves outside of the nerve fiber. When this occurs — and only the negative electricity is able to flow along the nerve fiber — human electrical current is rapidly established, putting to work a muscle or an organ. But, after the electrical current passes, everything returns to normal. The positive electricity returns to the outside of the nerve fiber and the negative electricity returns to the inside. In this way the nerve fiber becomes ready, once again, for another touch or stimulus.
Fuses
Without human electricity our body does not function. It becomes paralyzed or dies. Because of its importance we should know that the electrical system of our body is composed of 3 parts:
(1)
The brain, the central nervous system, is a marvelous computer.
(2) Spinal cord which is inside of the vertebral column and serves as an
electrical cable.
(3) The peripheral nerves — the electrical wires — which connect the
spinal cord to all parts of our body.
These three parts (Diagram) are interconnected by special electrical fuses, called synapses, which serve to prevent damage or burning out of the human electrical system. More than 95 percent of the physiological activities of our body are carried out automatically! We do not give orders to our heart to beat regularly, neither do we tell our stomach, our liver, kidneys, or lungs how they must fulfill their functions.
Because there are so many functions that take place automatically there is an absolute need for our human electrical system to be protected by many tiny electrical fuses! Everybody immediately associates sex with the genital organs. But the genital organs cannot work independently!
They depend on the electricity produced by the five senses — smell, vision, hearing, taste and touch (skin). Therefore, we must first study these five special electrical receivers in order to be able to understand normal sexual life.
