The term "intervertebral" refers to the space or structures located between the vertebrae in the spine. These spaces are crucial for providing flexibility and support to the spinal column, allowing for movement and shock absorption. The intervertebral discs, which are made of cartilage, act as cushions between the vertebrae, helping to prevent damage during activities like walking or lifting. Intervertebral structures also play a role in protecting the spinal cord, which runs through the vertebral column. Each disc consists of a tough outer layer called the annulus fibrosus and a gel-like center known as the nucleus pulposus. Together, these components help maintain the integrity and function of the spine.
