Separated into spaces or divisions, as by cancelli.In anatomy, same as in zoölogy, but especially said of the light spongy or porous texture of bone resulting from numerous thin osseous laminæ with intervening spaces large enough to be readily seen by the naked eye. Such texture occurs in the ends of long bones, as the humerus and femur, and in the interior of most short, fiat, or irregular bones. The spaces are chiefly vascular channels, filled with connective tissue, fat, etc., between plates or layers of more compact bone-tissue.In botany, applied to leaves consisting entirely of veins, without connecting parenchyma, so that the whole leaf looks like a sheet of open network; in mosses, applied to cell-structure having such appearance.Also cancellous.
