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 and Endosteum. Periosteum is a layer of vascular, innervated, dense connective tissue. surrounding the non-articular surfaces of bone. Perforating Fibers (also. called Sharpeyâs fibers) are collagen fibers that connect the periosteum to. the bone matrix. The endosteum is a thin layer of connective tissue that lines. the inside of the marrow cavity and any canals passing through the compact. bone. Both the periosteum and the endosteum membranes are osteogenic â. they contain cells that can produce bone.
