electro-, electr-, electri-

A colorimeter that uses a phototube or photocell, a set of color filters, an amplifier, and an indicating meter for quantitative determination of color.

Phototherapy (treatment of diseases by light) in which the source of the rays is an electric light.

1. A reference to the stimulation of the phrenic nerve in the diaphragm or the neck with the purpose of inducing a contraction of the hemidiaphragm, a diaphragm with normal muscle development only on one side.
2. Pertaining to the technique of stimulating electrically the phrenic nerve in the neck in order to induce contraction of the hemidiaphragm.

1. The electrical stimulation of the phrenic nerve, and is used to provide respiration or breathing for patients who have been paralyzed by an acute bulbar poliomyelitis (a severe form of viral disease affecting the medulla oblongata, which may result in a dysfunction of the swallowing mechanism, normal breathing, and circulatory distress).
2. An artificial respiration in which the nerves that control breathing are stimulated electrically through correctly placed electrodes.

3. An application of intermittent electrical stimuli to cutaneous electrodes over the phrenic nerves in the neck to rhythmically stimulate respiration or proper breathing.

The technique is used in patients whose respiratory center has been damaged.

An invasive electrodiagnostic or manometrc procedure that uses electrode catheters to pace the heart and potentially induce arrhythmias.

The test identifies defects in the heart conduction system and arrhythmias which are otherwise not apparent. It also is used to analyze the effectiveness of antiarrhythimic drugs.

A reference to or produced by electrophysiology; which is the science that studies the relationship between living organisms and electricity or the electrical activity associated with any part of the body and its functions).

Someone who studies or applies the processes of electrophysiology, which is a branch of biology concerned with the relationships between electric phenomena and biological functions.

1. The branch of medicine or biology dealing with the study of electric activity in human or animal bodies.
2. A branch of physiology that studies the relationship between electric phenomena and bodily processes.
3. The study of the electrical properties of living tissue.
4. The electric activity associated with a bodily part or function; such as, the effects of electrical stimulation on tissues, the production of electric currents by organs and tissues, and the therapeutic use of electric currents.
5. A branch of physiology concerned with determining the basic mechanisms by which electric currents are generated within living organisms.
6. The physiological production of electric phenomena in the normal human body.

1. The curving movement or growth of a plant in response to slight electric currents.
2. A turning toward or a turning away from a source of electrical energy.
3. The movement of a cell or organism in response to an electrical stimulus.

Individual electricity-producing cells in eels and other electric fish which are connected in a series-parallel arrays, similar to the miniature elements of a battery.

They are usually thin wafer-like cells, the two surfaces of which are distinctly different.

1. To deposit a metal on the surface of certain materials by using the process of electrolysis.
2. To effect the transfer of one metal to another one by using electrolysis.
3. To apply a metallic coating on a conductive surface with electrolytic actions.

1. The process of plating or coating a conducting surface with a metal by a process of electrolysis.
2. The electrodeposition of an adherent metal coating onto a conductive object for protection, decoration, or for other reasons; such as, securing a surface with properties or dimension that are different from those of the basic metal.
3. Electrodeposition (deposit on an electrode by electrolysis) of a metal or alloy from a suitable electrolyte solution.

The article to be plated is connected as the cathode in the electrolyte solution while direct electrical current is introduced through the anode which consists of the metal to be deposited.

4. The art or process of depositing a coating or cover; for example, silver, gold, or nickel on an inferior metal, by means of an electric current.

The metal to be deposited on an article is usually used as the anode and the article to be plated as the cathode, in an electrolyte solution in which the plating metal is the cation.

1. One of a number of flattened plates forming an electric organ in certain fish, consisting of modified muscle tissue having an electric charge.
2. One of the structural units of an electric organ of some fish, composed of thin, flattened plates of modified muscle that appear as two large, wafer-like, roughly circular, or rectangular surfaces.

Disc-shaped syncytial cells (cells that fuse with adjacent cells to form multinucleated large cells with fused cytoplasms), large numbers of which form a gelatinous substance in the electric organs of fish.

The immediate effects produced by the passage of an electric current through any part of the body: An electroplexy can cause a painful stimulation of nerves or contractions of the muscles.
