Which cartilage is present at the end of long bones?

Options

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

Answer

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

### Step-by-Step Solution:

1. **Understanding Long Bones**: Long bones are characterized by their elongated shape and are crucial for providing support and mobility to the body. Examples include the femur (thigh bone).

2. **Structure of Long Bones**: Long bones consist of a shaft (diaphysis) and two ends (epiphyses). The diaphysis is the long central part of the bone, while the epiphyses are the ends of the bone.

3. **Growth and Development**: The growth of long bones occurs primarily at the epiphyseal plates, which are located at the ends of the bones. This is where new bone tissue is formed, allowing the bone to elongate.

4. **Cartilage at the Ends**: The ends of long bones (epiphyses) are covered with a specific type of cartilage that plays a crucial role in joint movement and cushioning.

5. **Identifying the Type of Cartilage**: The cartilage present at the ends of long bones is known as **hyaline cartilage**. This type of cartilage is smooth and allows for frictionless movement at joints.

6. **Conclusion**: Therefore, the correct answer to the question is **hyaline cartilage**.

### Final Answer:
The cartilage present at the end of long bones is **hyaline cartilage**.
