Which cartliage is present at the joints of long bones?

Options

A. Calcified
B. Elastic
C. Hyaline
D. Fibrous

Answer

To answer the question "Which cartilage is present at the joints of long bones?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Question**: We need to determine which type of cartilage is found at the joints of long bones.

2. **Review the Options**: The options provided are:
- Option 1: Calcified cartilage
- Option 2: Elastic cartilage
- Option 3: Hyaline cartilage
- Option 4: Fibrous cartilage

3. **Evaluate Option 1 - Calcified Cartilage**:
- Calcified cartilage is indeed found at the ends of long bones, but it is not specifically the cartilage present at the joints. Therefore, this option is not the correct answer.

4. **Evaluate Option 2 - Elastic Cartilage**:
- Elastic cartilage is found in structures that require flexibility, such as the ears. It does not play a role in the joints of long bones. Thus, this option is incorrect.

5. **Evaluate Option 3 - Hyaline Cartilage**:
- Hyaline cartilage is a smooth, glass-like cartilage that covers the surfaces of joints. It is specifically present at the joints of long bones, allowing for smooth movement and reducing friction. This option is correct.

6. **Evaluate Option 4 - Fibrous Cartilage**:
- Fibrous cartilage is found in areas that require strong support, such as intervertebral discs. It is not present at the joints of long bones, making this option incorrect.

7. **Conclusion**: Based on the evaluations, the correct answer is **Option 3: Hyaline cartilage**.

### Final Answer:
The cartilage present at the joints of long bones is **Hyaline cartilage**.
