Decalcified Bone is :-a)Bone with organic matterb)Bone with Inorganic matterc)Bone without living cellsd)Bone without peristomiumCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

If bone is treated with HCl (acid) it's inorganic components especially calcium is removed (de calcified) and only organic components remain in the bone. Hence Option a is correct.
Hope u got it!

Answer

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

Answer

Decalcified Bone is:

Decalcified bone refers to bone tissue that has undergone a process called decalcification, which involves the removal of mineralized components, primarily calcium salts, from the bone matrix. This process allows for the preservation and study of the organic components of bone, such as collagen and other proteins, while the mineralized component is removed. Decalcified bone is commonly used in histological studies, where the focus is on examining the cellular and non-mineralized components of bone tissue.

Explanation:

Decalcified bone is bone tissue that has been treated with a decalcifying solution, typically containing a weak acid such as hydrochloric acid or ethylenediaminetetraacetic acid (EDTA). The purpose of this treatment is to remove the calcium salts that make up the mineralized component of bone, leaving behind the organic matrix.

Composition of Bone:

Bone is composed of both organic and inorganic components, which work together to provide its strength and flexibility.

Organic Matter:
- Collagen: The main organic component of bone is collagen, a fibrous protein that provides tensile strength and flexibility to the bone tissue.
- Other Proteins: In addition to collagen, bone also contains other proteins such as osteocalcin, osteonectin, and bone sialoprotein, which play important roles in bone formation and remodeling.
- Cells: Bone tissue is populated by several types of cells, including osteoblasts (bone-forming cells), osteoclasts (bone-resorbing cells), and osteocytes (mature bone cells embedded within the bone matrix).

Inorganic Matter:
- Hydroxyapatite: The mineralized component of bone is primarily composed of hydroxyapatite, a form of calcium phosphate. Hydroxyapatite crystals provide bone with its hardness and rigidity.

Decalcification of Bone:

The process of decalcification involves the removal of these hydroxyapatite crystals, leaving behind the organic components of bone tissue. Decalcified bone can then be sectioned, stained, and examined under a microscope to study the cellular and non-mineralized components of bone. This is particularly useful in histological studies, where the focus is on the cellular structure and function of tissues.

Conclusion:

In summary, decalcified bone refers to bone tissue that has undergone the process of decalcification, which involves the removal of mineralized components, primarily calcium salts. This allows for the preservation and study of the organic components of bone, such as collagen and other proteins. Decalcified bone is commonly used in histological studies to examine the cellular structure and function of bone tissue. Therefore, the correct answer is option 'A' - bone with organic matter.

Answer

Decalcified Bone is Bone with organic matter. Here's why:

- Organic matter in bone includes collagen and other proteins crucial for bone flexibility and strength.
- Decalcification removes the inorganic minerals like calcium phosphate, revealing the organic matrix.
- This process aids in studying bone structure and composition.
- Organic components provide bones with elasticity and help withstand stress.
- Understanding decalcified bone helps in research, medical diagnoses, and treatments.
