What Is an Intervertebral Disc?
An intervertebral disc is a flexible cushion between neighboring spinal bones called vertebrae. Each disc has a firm outer ring and a softer inner center. This structure helps the spine bear loads, bend, and move while maintaining space between vertebrae. Disc tissue can change with age, injury, or repeated stress.

Key Takeaways About Intervertebral Disc
- Each disc has a firm outer ring and softer inner center.
- Disc condition can affect spinal movement and nerve space.
- A disc is not the same structure as a vertebra.
How Intervertebral Disc Works
An intervertebral disc works as a load-sharing cushion between adjacent vertebrae. Its outer ring contains the softer inner center, which helps distribute force as the spine bends, straightens, or carries weight. Disc height also helps preserve openings where spinal nerves pass.

Spinal decompression therapy considers how pressure and positioning affect the spaces around a disc. A clinician reviews the person’s symptoms, movement patterns, and available examination findings before selecting an approach. A vertebra is the bone above or below the disc, while the spinal cord is nervous tissue inside the spinal canal. These structures work near one another but have different roles.
From the Advanced Injury Care Clinic team
When we assess an intervertebral disc during spinal decompression therapy, we consider the involved spinal region, movement tolerance, and reported symptoms. Our team also distinguishes disc-related findings from muscle, joint, or nerve concerns so the treatment plan reflects the full clinical picture.
Intervertebral Disc in Practice: A Real-World Example
A person with low back discomfort may have symptoms that change with sitting, bending, or standing. During spinal decompression therapy, we consider the lumbar disc region and adjust the approach according to the person’s examination findings and tolerance.
