The periosteum is the membrane around the shaft of a long bone.
Osteoclasts break down bone (osteo-=bone, -clast=breaks) and osteoblasts build bone. (-blast=builder). This osteoclasts is on the surface of the bone. Usually breaking down and building up of bone is in equilibrium.
It is the endosteum.

Those "membranes" are called periosteum. The periosteum is how bone gets part of its blood supply.
periosteum
Peri means around and osteum means bone. So periosteum means the structure that surrounds the bone. This fallows that you have endosteum inside the long bones. Also that you have two layers of periosteum for flat bones of the skull bones and no endosteum there. (This layer acts as barrier between the bone and other tissues that is attached to bones.)
Osteoblast are made in three areas of bone periosteum, endosteum, and the haversian canal.

Like the periosteum, the endosteum contains both osteoblasts and osteoclasts.compound bone
