The major function of the intervertebral discs is to

Options

A. absorb shock
B. string the vertebrae together
C. prevent injuries
D. prevent hyperextension

Answer

### Step-by-Step Solution:

1. **Understanding Intervertebral Discs**: Intervertebral discs are structures located between the vertebrae in the spine. They are made of fibrocartilage, which is a tough and flexible tissue.

2. **Function of Intervertebral Discs**: The primary role of these discs is to act as cushions between the vertebrae. They help in absorbing shock during activities such as walking, running, and jumping.

3. **Impact Absorption**: When there is an impact or pressure on the spine, the intervertebral discs compress, which allows them to absorb the shock. This prevents the vertebrae from colliding with each other and minimizes the risk of injury.

4. **Formation of Joints**: Intervertebral discs also contribute to the formation of fibrocartilaginous joints between the vertebrae, allowing for some movement and flexibility in the spine.

5. **Conclusion**: Considering all the functions, the major function of the intervertebral discs is to **absorb shock** and protect the vertebrae from damage during physical activities.

### Final Answer:
The major function of the intervertebral discs is to **absorb shock**.
