What is an electric shock?
Electric shock occurs when the electric current from the outer source flows through the tissues of the human body. Shock may be caused by static electricity or contact with energy source such as a battery or electric line. The human body can be damaged by electric shock, as the flow flow can disrupt the normal functioning of the nervous system or at higher levels cause serious burns as it passes through the body. Electric shock can also be used as a medical treatment, usually to repair problems with the functioning of the nervous system of the body.
People are quite sensitive to electricity, in a small part, because our nerves rely on electrical impulses to carry information. Dokonce i množství proudu generovaného 12-voltovou baterií je obvykle patrné citlivějšími částmi nervového systému. However, to perceive the electric current as a shock, it will usually be necessary to be either sudden, as in a sudden discharge of bostation, or stronger, such as contact with electric fence or household.
roles played by electrical impulses in the functioning of the nervous system is the root of one of the main hazards of electric shock. Nerves use electricity to transmit information. A sufficiently large dose of electricity can easily overcome the normal electric charge of the nervous system and can leave the nerves locked in the activated state. This process can lead to a jerking in the muscle system or, more seriously, may disrupt the normal rhythm of the heart.
Another source of danger from the electric impact stems from the fact that the human body is mainly made up of water, and is therefore adequate, although not an ideal, electricity conductor. This allows electricity to pass through the body, but ensures that if it does, it causes damage, because the waste heat is go -to -date when the current overcomes the natural resistance of the body. When a person is exposed to a very powerful electric current, this heat is relatively intense and sonsObser serious burns throughout the body, damage that often turns out fatal, although the initial disturbance of the nervous system is not.
Electric shock can also be used to treat the body. Electroconvulsive therapy relies on electric shocks to reset the nervous state of the brain, which can cause nerve problems over time that arise from unhealthy chain missiles of specific neurons to be dispersed. Electric shock can also be used to restart the human heart or to repair the wrong beating of the heart in which the right rhythm was disrupted.
