Extract

The influence of slight variations in the inorganic constituents of the tissue fluids on the function of the nervous system has long been the subject of physiological investigation. Thus a disturbance of the ratio Ca/Na is known to be related to the irritability of muscular tissue (1). Ca and K are antagonistic in their action on the vegetative nervous system: Ca increases the excitability of the sympathetic system, whilst K excites the parasympathetic system (2). The influence of Ca on the excitability of the central nervous system finds a clinical illustration in tetany; and, from a pathological point of view, diminution of the serum Ca is well established in certain types of this disorder.
