A person who has a herniated disc may experience pain that affects their daily activities. While it is not always necessary, some people may require herniated disc surgery to alleviate pain and other symptoms.

TVertebrae are the separate bones that make up the spine. The cartilage discs that lie between the vertebrae are known as lumbar discs.

The cervical discs' roles include supporting the spine and serving as shock absorbers between the vertebrae.

The human spine typically has 23 discs. Each disc consists of the following three parts:

• The inner, gel-like component of the disc called the nucleus pulposus is what gives the spine its strength and flexibility.
• The nucleus pulposus is protected by an outer layer called annulus fibrosis.
• Endplates made of cartilage called cartilaginous endplates are located between the disc and the adjacent vertebrae.
