Ends of the long bones are covered by

Options

A. tendons
B. cartilage
C. ligaments
D. blood cells

Answer

**Step-by-Step Solution:**

1. **Identify the Structure of Long Bones**: Long bones, such as the femur, have distinct regions: the epiphysis (ends), metaphysis (between the epiphysis and diaphysis), and diaphysis (shaft).

2. **Define the Epiphysis**: The ends of long bones are referred to as the epiphysis. This is the area that articulates with other bones at joints.

3. **Understand the Covering of the Epiphysis**: The epiphysis is covered by a type of cartilage. This cartilage serves a crucial role in joint function.

4. **Specify the Type of Cartilage**: The cartilage that covers the epiphysis is primarily hyaline cartilage, which is also known as articular cartilage.

5. **Explain the Function of the Cartilage**: Hyaline cartilage provides a smooth surface for joint movement and helps in the attachment of bones at joints.

6. **Clarify Misconceptions**: It is important to note that tendons attach muscles to bones, ligaments connect bones to other bones, and blood cells do not cover the epiphysis.

7. **Conclude the Answer**: Therefore, the ends of long bones are covered by cartilage, specifically hyaline cartilage.

**Final Answer**: The ends of the long bones are covered by cartilage (hyaline cartilage).
