electro-, electr-, electri-

(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)

Electronics in our lives consists of numerous tools

Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.

megaelectronvolt, megaelectron volt, MeV
A unit of energy commonly used in nuclear and particle physics, equal to the energy acquired by an electron in falling through a potential of 1,000,000 volts.
megaelectronvoltcurie, megaelectronvolt-curie
A unit of radioactive power, equal to the power generated by one curie emitting an average energy of 106 electronvolts per disintegration.
monopolar electrocautery, unipolar electrocautery
An electrocautery (electrosurgery) in which an electric current is applied through a hand-held active electrode and travels back to the generator through an inactive electrode attached to the patient (the grounding pad), so that the patient is part of the electrical circuit.
monopolar needle electrode
A needle electrode consisting of a single piece of stainless steel wire coated with insulating material except at the tips.

It must be accompanied by another electrode as a reference.

monopolar stimulating electrode
A stimulating electrode which has the two terminals attached separately and relatively far apart.
moving boundary electrophoresis
An electrophoretic technique (movement of electrically charged particles in a fluid or gel) in which an optical system is used to observe and to measure the electrophoretic movement of the distinct boundaries in a suspension.
multilead electrode, multielectrode
An electrode composed of a number of insulated wires inside a metal cannula, with their bare tips at apertures, or openings, flush with the outer circumference of the cannula (small flexible tube inserted into a body cavity for draining off fluid or introducing medication).

It is used to determine the territory of a motor unit.

multiple point electrode
1. An electrode with many contacts for recording from many sources, as from different depths in the brain.
2. Several sets of terminals providing for the use of several electrodes.
myoelectric prosthesis (s) (noun), myoelectric prostheses (pl)
An advanced device operated by battery-powered electric converters that are activated through electrodes provided by muscles: A myoelectric prosthesis uses electromyography signals from voluntarily contracted flexors within a person's elbow, wrist rotations, or hands that open and close the fingers.

A myoelectric prosthesis utilizes the remaining nerve and neuromuscular systems of the human body to control the functions of an electrical operated prosthetic hand, wrist, elbow, or foot.

National Electrical Manufacturers Association, NEMA
This national organization establishes certain voluntary industry standards relating to electric motors for some non-electronic products; such as, junction boxes.

These standards refer to the operating characteristics, terminology, basic dimensions, ratings, and testing of products that are used in utility, medical imaging, industrial, commercial, institutional, and residential applications.

needle electrode
A thin, cylindrical electrode with an outer shaft beveled to a sharp point, enclosing a wire or series of wires which can explore the activity of single motor or nerve units of the body or stimulate them.
negative electricity
1. An electric charge caused by an excess of negatively charged electrons.
2. The form of electricity in which the electron is the elementary unit.
negative electrode
A cathode; the pole by which electric current leaves the generating source.
negative electropism
The movement of a cell or an organism away from an electrical stimulus.
negative electrotropism
The movement of a cell or an organism away from an electrical stimulus.
