It's the part you see when you look at a skeleton. At the outer edges of compact bone, rather than being arranged in osteons, the osseous tissue is arranged in circumferential lamellae. It accounts for about 80 percent of the total bone mass of the adult skeleton. T/F: Perforating fibers anchor the endosteum to the superficial surface of a bone.
