Bone Endosteum Anatomy. The outer surface of bone is covered by periosteum which is bound to bone by bundles of collagen fibers known as Sharpeys fibers and the inner bone surface is lined with endosteum Fig. Bone consists of highly calcified intercellular bone matrix and three types of cellsosteocytes osteoblasts and osteoclasts.
A long bone is organized into periosteum which includes an outer fibrous and inner cellular layer that contains osteoblasts compact bone. Yellow bone marrow contains mesenchymal stem cells producing skeletal tissues cartilage bone and fat. Bone cannot be bare.
It is important to note that the absence of endosteum or periosteum on a bone signals that the bone is ready to be reabsorbed by osteoclasts.
A hard outer layer that is dense strong and durable. Endosteum The endosteum is a thin lining of the medullary cavity. It is important to note that the absence of endosteum or periosteum on a bone signals that the bone is ready to be reabsorbed by osteoclasts. Oste- bone where bone growth repair and remodeling occur.
