calci-, calc-, calcane-, calcio-, calco-, calcar-, calx

(Latin: lime, calcium; heel, bone of the tarsus; to tread; derived from calx, calcis, "limestone, lime, pebble"; from Greek words halix and psephos, "small stone, pebble".)

Fixation of calcium in the tissues, an occasional cause of tetany in infants.

Tetany refers to the hyperexcitability of nerves and muscles resulting from a decrease in the concentration of extracellular ionised calcium.

This may be associated with such conditions as parathyroid hypofunction, vitamin D deficiency, and alkalosis; or it may result from ingestion of alkaline salts.

It is characterized by carpopedal spasm (spasms or synchronous contractions of the neck, hands, and feet), muscular twitching and cramps, laryngospasm (spasm of the vocal cords and epiglottis) with inspiratory stridor (harsh sound heard during inhalation caused by air passing through a constricted passage), hyperreflexia (exaggerated reflexes), and choreiform (loss of neuronal functioning) movements.
