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.
At this time the main function of perioteum is to shield the bone from harm. Ad. However, the progenitor cells of the inside layer of the periosteum have the ability to transform into a different type of cell called chrondroblasts.These cells create cartilage cells called chondrocytes. Cartilage is a tough yet flexible material not quite as hard as bone.hese are responsible for regenerating or replicating new cells. The function of periosteum cells is to develop into new cells as a bone grows but it does not have the ability to replicate indefinitely.
