What Is the Difference Between Spongy and Compact Bone?

Spongy bone (cancellous bone) is a bone tissue with many irregular spongy bone marrow cavities. That is generally called bone cancellous. The quality of dense bone is also the bone cancellous morphology, and it is formed after the reconstruction process through the reconstruction of osteoblasts and osteoclasts. After the ossification is completed, the spongy bone remains in the cavity of the long bone and the cavity of the flat bone, but the arrangement of the bone tissue at this time is consistent with the direction of the force added to the bone, so Able to withstand mechanical pressure. Bone cancellous is covered with bone densities on the outside, but there are exceptions. For example, the parts of the upper and lower metatarsal bones that are connected to the teeth (alveolar pars alveolaris) are not covered with bone dense, but are exposed directly outside. ^[1]
