Periosteum is a membrane that lines the outer surface of all bones, except at the joints of long bones. Endosteum lines the inner surface of all bones. Periosteum connsists ofâ¦ dense irregular connective tissue. Periosteum is divided into an outer fibrous layer and inner cambium layer (or osteogenic layer). The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts. These osteoblasts are responsible for increasing the width of a long bone and the overall size of the other bone types.
Periosteum is a very thin membrane that covers many of the bones in your body. It serve as protection as well as a channel for the blood supply and nutrients for bone tissue. In this lesson, you will learn exactly what periosteum is and the function that it serves in our skeletal system.his layer of the periosteum also helps get nutrients to the bone tissue-Volkmann canals allow for the blood supply from the periosteum to enter into the bone tissue. The inner periosteum contains cells responsible to bone repair and growth.
