Cross-pieces or reticulations forming a latticework or grating.In zoology and anatomy, the reticulations or intersections constituting cancellated structure or reticulated texture; a composition of many spaces bounded by lines or surfaces forming a network or lattice-like arrangement, such as the light, spongy, cancellated tissue of bones. The word is little used except for this kind of osseous texture, and the singular, cancellus, is not in use. See cancellate, .
