Calcigerous

1839, R. Harlan, letter to the editor, J. V. C. Smith (editor), The New England Journal of Medicine, Volume 20, page 72, These calcigerous tubes do not run in a straight line, but their general tendency is a curvature upwards, and, in addition to which, each line or tube is distinctly waved in itself.

The cement is traversed by numerous fine calcigerous tubes continued in many parts from those of the hard dentine, but having a less regular course, which is however generally at right angles to the surface: they terminate principally in minute branches, which form a rich plexus around the calcigerous cells with which they communicate.

From 89-95 per cent of all urinary calculi are reported as being calcigerous in nature.^(12, 33)
