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).

These osteoblasts are responsible for increasing the width of a long bone and the overall size of the other bone types.
