electro-, electr-, electri-

An altered condition of excitability of a nerve or muscle which is produced when it is in the electrotonic state.

1. The potential led off by electrometers on either side of bipolar electrodes when a nerve is being stimulated by direct current.
2. The potential developed by cells as a result of metabolic activity and circuited (path for electrical current to flow) through surrounding tissue.

A gap junction which transmits electrical impulses in electrically excitable tissue.

A gap junction is an intercellular network of protein channels that facilitates the cell-to-cell passage of ions, hormones, and neurotransmitters.

1. The altered excitability, conductivity, or electrical condition of a nerve which is produced when a constant electric current is passed through it.
2. A change in the condition of a nerve or a muscle during the passage of a current of electricity.
3. The altered electrical state of an excitable body cell when a constant electric current is passed through it; for example, the changes in membrane potential of excitable cells that cause a passive change in potential at every other point on the body's cell membrane.
4. The transient change of irritability in a nerve or a muscle during the passage of a current of electricity.

An electrically operated trephine (an instrument used for removing a disk of bone, primarily from the skull) for perforating or entering the skull.

1. The movement of a cell or organism in response to an electrical stimulus.
2. A bodily orientation in relation to an electric current.
3. A curvature of sessile (permanently attached) organisms toward or away from an electrical current stimulus.

A small electric turbine placed into the arterial bloodstream for the purpose of measuring blood flow.

1. A metal-plated molded replica of a relief printing plate, produced electrolytically.

It is used for long press operations.

2. A reference to a duplicate printing surface prepared by making a mold of the type page or halftone plate, then by suspending this mold in a bath of copper sulfate and sulfuric acid so that, by electrolytic action, a thin shell of copper is deposited on it, and finally the pouring of molten type metal into this shell in order to strengthen it for use on a printing press.
3. A duplicate of a block of type or engraving made by electroplating a wax, lead, or plastic mold of the original or an item that has been printed from an electrotype.

Someone whose work involves the making of electrotypes which are the metal or composition plates used in printing.

A machine that through electrically transmitted messages automatically sets type.

Newspapers that use it can publish simultaneously in many cities.

Having to do with or made by means of electrotyping or the process of making electrotypes (the metal or composition plates used in printing).

1. The production of printing plates by electroforming.
2. The process of making an electrotype or the art or process of electrotyping something by employing, or producing by, the process of electolytic deposition; such as, a galvano-plastic copy of a medal, etc.

Someone who is skilled in electrotyping.

The ultrafiltration or separation of colloidal or very fine solid materials by filtration through microporous or semipermeable media brought about by electro-osmosis.

Electromyography (recording and study of the intrinsic electrical properties of the skeletal muscle) in which the action potentials produced by peristalsis (rippling motions of muscles) of the ureter are recorded.
