Names of Diseases and Terms Defined in the Text Are Omitted.
Ampere. The unit of current strength or intensity.
Anemia. A deficiency in quantity or quality
of the blood.
Arteriole. A small artery.
Asepsis. Freedom from septic matter or infection.
Atonic. Lacking tone.
Atrophy. Wasting of a part.
Bi-polar. Attached to both poles of the apparatus.
Capillaries. Hair-like vessels connecting
the arterioles with the smallest veins.
Carbon dioxide. CO2. A poisonous
gas eliminated through the lungs.
Carbon dioxide snow. Under high pressure
the gas liquefies and on liberation the evaporation produces snow-like
crystals which are moulded and applied to a growth that is to be removed.
It is frozen and separates in 10 to 12 days without leaving a scar.
Cataphoresis. Driving a substance into the
tissues by means of an electric current.
Coagulum. A clot.
Condenser electrode. A vacuum tube containing
a metal disk which acts as one plate of a condenser, the tube wall being
the di-electric and the body surface in contact, the other plate. Shown
in Fig. 21.
Conductor. A material readily transmitting
Contra-indicted. Not indicated.
Dermatitis. An inflammation produced by an
overdose of the X-ray, or X-ray "burn."
Di-electric. A substance separating two charges
of electricity in a condenser, as the glass in a Leyden jar.
Diplopia. Double vision.
Effleuve. The fine spray from a vacuum tube
or other electrode, too fine to be termed a spark.
Electrolysis. Breaking up a compound into
its elements by means of an electric current. Electric analysis.
Elimination. Carrying a substance out of
Endarteritis. Inflammation of the lining
of an artery.
Exudate. A substance deposited in or on a
tissue, either by vital action or by disease.
Functional. Pertaining to the natural action
of a part, which may vary somewhat without an actual change in the structure
of the organ or part.
Hemoglobin. The coloring matter of the red
blood corpuscles, containing iron.
Hyperemia. An increased amount of blood.
Hyperplasia. Abnormal increase in tissue
Hypertension. Above normal pressure.
Hypotension. Less than normal pressure.
Ion. A moving particle of electricity.
Indican. A substance found in the urine as
a result of imperfect intestinal digestion (from proteid putrefaction).
Inductance. The phenomenon of induction.
Induction. The generation of an electric
current in a body by the influence of another electrified body.
Inhibitive. Producing inhibition.
Inhibition. Soothing or arresting a process
Intra-ocular. Within the eye.
Intra-vaginal. Within the vagina.
Lesion. A disease or diseased area.
Leucocytosis. An increase in the number of
white blood cells.
Metabolism. The process of changing inorganic
materials into living cells.
Milliampere. One one-thousandth of an ampere.
The unit of dosage of medical electricity.
Modality. Any one of the different forms
Monopolar. Connected to one pole.
Myelocyte. A pathological white blood cell
found in leukemia.
Neurosis. A nervous disease, especially a
Ohm. The unit of resistance to the passage
of an electrical current.
Orificial. Pertaining to one of the openings
or orifices of the body.
Oxidation. Combining or causing to combine
Oxyhemoglobin. Hemoglobin charged with oxygen
in the arterial blood.
Phagocytosis. The destruction of harmful
cells by cells called phagocytes which envelop and absorb them.
Physiological. Natural or normal.
Plastic. Tending to build up or form tissues,
as a plastic exudate.
Poikilocytes. Malformed, over-sized, non-nucleated
red blood corpuscles present in pernicious and other anemias.
Potential. Electric pressure (measured in
Reciprocal. The reciprocal of a fraction
is the inversion of it. Thus the reciprocal of ½ is 2/1 or 2.
Serosanguinous. Serum and blood mixed.
Solenoid. A coil of wire.
Suppurative. Tending to form pus.
Supra-orbital. Above the orbit or eye.
Tension. 1. Electromotive force; potential.
2. Pressure, as the pressure of blood in the arteries.
Thermostat. An apparatus registering heat
expansion or regulating a mechanism through this action.
Transformer. A coil that changes the voltage.
If it increases it, it is called a "step-up" transformer.
Unipolar. Connected to one pole; same as
Volt. The unit of electrical pressure.
