, and three others, (short, irregular, sesmoif). Long bones, such as the humerous, are made up of a long shaft made of compact bone and contain a cavity which is filled with bone marrow. Flat bones are mainly found in the skull and are made of two thin layers of compact bone, with a layer of cancellous bone in between them.
