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.
The function of periosteum is to also provide blood and nutrients to the bone. The periosteum is attached to the bone by resilient collagen fibers called Sharpeyâs fibers. Also referred to as bone or perforating fibers, this network of strands binds this protective membrane to the entire 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.
