compact tissue

As the hair grows through this matted substance it is subjected to the same process, until, in the course of years, a compact substance is formed like a strong felt, about an inch and a half thick, that has been trained into the shape of a helmet.

The long, narrow medullary cavity is enclosed in a strong wall of compact tissue which is thickest along the interosseous border and dorsal surface.

The skull was broken and the bones had an orange/yellowish cast, a vitreous texture, and porous and compacted tissue.

The head, processes, and the thickened parts of the bone, contain cancellous tissue; the rest consists of a thin layer of compact tissue.

Compact tissue is synonymous with cortical bone, and spongy tissue is synonymous with trabecular and cancellous bone.

In the cranial bones, the layers of compact tissue are familiarly known as the tables of the skull; the outer one is thick and tough; the inner is thin, dense, and brittle, and hence is termed the vitreous table.
