MICROANATOMY

Detailed explanation-1: -Compact bone is the denser, stronger of the two types of osseous tissue (Figure 6.3. 6). It makes up the outer cortex of all bones and is in immediate contact with the periosteum. In long bones, as you move from the outer cortical compact bone to the inner medullary cavity, the bone transitions to spongy bone.

Detailed explanation-2: -Osteons in compact bone tissue are aligned in the same direction along lines of stress and help the bone resist bending or fracturing.

Detailed explanation-3: -Cortical Bone: consists of about 80% of the total bone in the body and is much stronger than trabecular bone. It is very resistant to bending, torsion, and compression and is much more dense with a minimal role in metabolism.

Detailed explanation-4: -Both types of bones contain osteoblasts and osteoclasts that are necessary for creating bones. Both compact and spongy bones contain proteins like collagens and osteoids, which mineralize to help in bone formation. There are inorganic mineral salts deposited in the matrix of both spongy and compact bones.
