Hardest tissue of the body is

Options

A. Cartilage
B. Fibrous connective tissue
C. Bone
D. Areolar tissue

Answer

**Step-by-Step Text Solution:**

1. **Identify the Options**: The question asks for the hardest tissue in the body. The options provided are cartilage, fibrous connective tissue, bone, and areolar tissue.

2. **Evaluate Cartilage**:
- Cartilage is a soft skeletal tissue.
- It is not rigid like bone; instead, it is flexible and can bend.
- It is found in various parts of the body, such as the nose and ear pinna, but it is not the hardest tissue.

3. **Evaluate Fibrous Connective Tissue**:
- Fibrous connective tissue can be categorized into dense regular and dense irregular types.
- It contains fibers and a fluid matrix, making it flexible rather than hard.
- Therefore, it cannot be considered the hardest tissue.

4. **Evaluate Bone**:
- Bone is known to be the hardest tissue in the body.
- It is composed of calcium and phosphate salts, which contribute to its hardness.
- Bones form through a process called ossification, where cartilaginous structures become hard due to the deposition of these salts.
- Thus, bone is the correct answer.

5. **Evaluate Areolar Tissue**:
- Areolar tissue is a type of loose connective tissue.
- It is widely distributed in the body and contains fine threads and air spaces, making it flexible.
- It is not rigid and therefore cannot be classified as the hardest tissue.

6. **Conclusion**: After evaluating all the options, the hardest tissue of the body is bone.

**Final Answer**: The hardest tissue of the body is bone.
