These cells can be of three types: osteoprogenitor cells (bone tissue stem cells), osteoblasts, or osteoclasts. Osteoblasts constitute the majority of the cells lining<br \/>\nthe anterior surface, and together they constitute a layer called the endosteum (highlighted in light blue).<br \/>\nThe endosteum is generally a very thin layer, often formed by a layer of cells arranged over the bone matrix.<br \/>\nSee on the next page that the endosteum lines not only the large bone cavities (e.g., the medullary canals), but also all the small cavities located between the trabeculae of the cancellous bone and even the inner wall of the Haversian canals.<br \/>\nOsteocytes are highlighted in green.<br \/>\n<\/div><\/div>\n<div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\"> <\/p>\n<div onclick>\n<div class=\"image-container\">\n<div class=\"extra\">\n<a href=\"javascript:void(0)\"><img decoding=\"async\" src=\" http:\/\/mol.icb.usp.br\/wp-content\/uploads\/7-22.jpg \" onmouseover=\"this.src=' http:\/\/mol.icb.usp.br\/wp-content\/uploads\/7-22-MO.jpg'\" onmouseout=\"this.src=' http:\/\/mol.icb.usp.br\/wp-content\/uploads\/7-22.jpg'\" \/><\/a><\/div>\n<p>Periosteum and endosteum.
