Explanation:
Detailed explanation-1: -Compact bone tissue forms the outer layer of all bones while spongy or cancellous bone forms the inner layer of all bones. Spongy bone tissue does not contain osteons.
Detailed explanation-2: -Osteons are only found in compact bone tissue. Rather than the cylindrical structures of osteons, spongy bone is made of rod and plate structures called trabeculae. This is necessary to help spongy bone form its porous structure, the structure that gives the bone its sponge-like appearance.
Detailed explanation-3: -Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow).
