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

Hint: The bone decalcification is the softening of bones because of the removal of calcium ions. This can be performed as a histological technique to study the bones and the DNA extract. This can also occur naturally during bone development and growth.

Step by step answer:Whenever we use the bone with the diluted hydrochloric acid it results that the inorganic salts present there have been removed from the bone and hence only the organic matter remains. Such a type of bone with only organic matter is known as the decalcified bone.
The bone decalcification is the removal of calcium ions from the bone with the help of a histological process, which makes the bone flexible and easy for the pathological investigation. This is necessary in order to obtain the soft sections of the bone using the microtome. Every thin section cut can be processed like any other soft tissue of the body.
The decalcified bone is the bone with organic matter.
Therefore, the correct answer is option A.

Note: The decalcification defines the technique used for removing the minerals from the bone or from the other calcified tissue by which the good-quality paraffin sections can be prepared and it will preserve all the essential microscopic elements.
The decalcification of the calcified cartilage and the bone is undertaken to soften the tissue for subsequent segmentation and ultramicrotomy. This is important for densely mineralized tissues, such as the mature long bones and the teeth.
