grapho-, graph-, -graph, -graphy, -grapher, -graphia
(Greek: to scratch; to write, to record, to draw, to describe; that which is written or described)
As indicated at the bottom of this page, there is a significantly large number of graphic word-entry groups in this unit. Such an extensive listing is provided to show how important the grapho- element is to the English language.
A neuron or neurone is an excitable cell specialized for the transmission of electrical signals over long distances.
2. A device for recording a person's gait or manner of walking.
2. A device used for recording the electrical activity of the myocardium (heart muscle) to detect transmissions of the cardiac impulses through the conductive tissues of the muscle.
Electrocardiography allows for the diagnosis of specific cardiac abnormalities.3. An instrument for recording the waveforms of voltages developed in the chest and lower parts of the human body in synchronism with the action of the heart.
4. An instrument used for making electrocardiograms.
I contains a lead-switching network, a differential amplifier, and a strip-chart recorder to trace the electrocardiogram on paper output.
2. A record, made by the electrocardiograph, which varies with the site of the electrode.
These plates are attached to a recording instrument, and they pick up the electrical impulses of the heart during which small changes occur as the heart beats. The normal form of these beats is altered by heart disease.2. The creation and study of graphic records produced by electric currents originating in the heart and the interpretation of electrocardiograms: Electrodes connected to a recording machine are applied to the chest, wrists, and ankles. 3. The specialty or science of recording and interpreting the electrical activity of the heart: An ECG, or EKG, can be taken at home, in the physician's office, or in the hospital where a 24-hour record can be obtained from a tape recorder worn by the patient.
2. A chemical separation technique in analytical chemistry, biochemistry, and molecular biology which is used to resolve and to separate mostly large biomolecules; such as, proteins.
Electrochromatography is a combination of size exclusion chromatography (gel filtration chromatography) and gel electrophoresis.
The term "gel" in this instance refers to the matrix used to contain, then separate the target molecules.
2. The measurement of electrical activity produced when the cochlea is stimulated.
A needle electrode is passed through the eardrum and placed on the cochlea, the part of the inner ear concerned with hearing. The electrical activity is then recorded.3. A diagnostic test in which a probe is inserted into the cochlea in the inner ear to measure and to record electrical activity.
Certain kinds of distortions may indicate the presence of disease.
