A conductor which enables a current to go in or out of a particular object, substance or region.
A locomotive that can operate with either electric or diesel power.
Magnet constructed from a soft iron core around which is wound a coil of wire. A magnetic field is generated when an electric current is passed through the wire.
Use of magnetism to produce an electromotive force (emf). If a bar magnet is pushed through a wire coil, an electric current is induced, in the coil, as long as the magnet is moving. By the same principle, an electric current is induced in the coil if it is rotated around the magnet,
An electron microscope uses a beam of electrons, instead of light, to produce highly magnified images of objects. As electrons have a much smaller wavelength than visible light, this allows a much higher resolution to be achieved
The process of separating electrons in a solution by passing an electric current through it.
Branch of physiology that is concerned with the electric phenomena in living bodies.
mechanical device that produces static electricity, or electricity at high voltage and low continuous current.
The passing of electric currents through the body's tissues to stimulate the functioning of nerves and the muscles.
machine used to deliver therapeutic electric shocks to patients
Condition in which there is large swelling of the tissues due to blockage of lymph vessels. It is usually caused by parasitic worms.
The application of chemical preservatives to slow the natural decomposition of a corpse. Modern methods were greatly refined in the 1800s. Although they have been widely used in Europe, the custom remains most commonly used in North America. Formaldehyde is the primary embalming fluid used today. It is a preservative injected into the blood system to replace the blood which is drained out. Embalming fluid can also be pumped into the body cavities as well.
Producing raised letters or designs on a surface.
A machine which creates a three-dimensional image or design in paper or other ductile materials.
An animal or human at an early stage of development, before birth. In humans the term refers to an unborn child up to the eighth week of development.
A substance that causes vomiting.
an instrument to look at the internal parts of the body. The modern endoscope is a flexible, fibreglass instrument that can be swallowed by a patient or introduced through a tiny incision in the body.
Inhalation anaesthesia technique in which anaesthetic and respiratory gases pass through a tube placed in the trachea via the mouth or nose.
A flexible tube inserted nasally, orally, or through a tracheotomy into the trachea to provide an airway
A liquid injected into the anus. Enemas can be carried out for medical reasons, as a treatment for constipation, or as a way to give drugs.
