What is one purpose of the intervertebral discs?

• A. To prevent movement between the vertebrae
• B. To aid in energy storage
• C. To provide cushioning and support
• D. To form new bone tissue

Answer: (C)

The intervertebral discs play a crucial role in maintaining the structural integrity and functionality of the spine. Their primary purpose is to provide cushioning and support between the vertebrae. Each disc is composed of an outer fibrous ring known as the annulus fibrosus and a gel-like center called the nucleus pulposus. This structure allows the discs to absorb shock and distribute loads more evenly across the spinal column during activities such as walking, running, or lifting. Additionally, the flexible nature of the discs permits movement and flexibility of the spine while preventing bone-on-bone contact, which could lead to injury. This cushioning effect is essential for maintaining comfort and mobility in daily activities. Thus, the option describing the function of the discs as providing cushioning and support accurately reflects their critical role in spinal health and mechanics.
