Answer:
Explanation:
Bone, or osseous tissue, is a connective tissue that constitutes the endoskeleton. It contains specialized cells and a matrix of mineral salts and collagen fibers.
The mineral salts primarily include hydroxyapatite, a mineral formed from calcium phosphate. Calcification is the process of deposition of mineral salts on the collagen fiber matrix that crystallizes and hardens the tissue. The process of calcification only occurs in the presence of collagen fibers.
The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 19.16).
All of these are characteristics of compact bone except 'containing bone marrow'.
The characteristics of a compact boneThe compact bone is one of the types of bone found in the human skeletal system that is made up of organic ground substance and inorganic salts.
It is the main structure in the body for support, protection, and movement due to its strong nature.
Bone cells in compact bone are reached by blood vessels and nerves that run through the central and perforating canals.
Bone marrow is a semi-solid tissue found within the spongy bone ,but not compact bones, and has many blood vessels.
Therefore, compact bone does not contain bone marrow.
