Question

Decalcified bone is

• A. Bone with organic matter
• B. Bone with inorganic matter
• C. Bone without living cells
• D. Bone without periosteum

Answer 1

The correct option is A Bone with organic matter

Decalcified bone is a bone with organic matter. Bone decalcification is the removal of calcium ions from the bone through a histological process, thereby, making the bone flexible and easy for pathological investigation. This is necessary in order to obtain soft sections of the bone using the microtome. Every thin section cut can be processed like any other soft tissue of the body. When the bone is treated with dilute hydrochloric acid, the inorganic salts are removed from the bone and the only organic matter is left. This type of bone with only organic matter is called as decalcified bone.
