Page 292 - point of entrance of a motor nerve into a muscle ; over such a point the application of a suitable current will produce contraction of a muscle in health. Of chief importance in testing for reaction of degeneration. The points on the surface of the body where the various branches of the motor nerve supplying the muscles may be best affected by electricity.
Page 293 - emitted from the source of radiant energy excited by a discharge of electricity within a vacuum tube, not deviable by a magnet or refracting medium ; they pass through opaque bodies, cause certain substances to fluoresce, affect a photographic plate like light rays, and they have peculiar therapeutic and pathological effects upon living tissue.
Page 292 - are said to be parallel when the positive elements are all connected to each other, and the negative are similarly connected. The EMF is only equal to the EMF of one cell, but its internal resistance is diminished in proportion to the number of cells thus joined. See SERIES.
