How do the discs and vertebrae help your spine?

The discs and vertebrae work together to provide support, flexibility, and protection for the spine.

Discs

The discs are located between the vertebrae and act as cushions or shock absorbers. They are composed of a tough outer layer (the annulus fibrosus) and a soft, gelatinous center (the nucleus pulposus). When pressure is applied to the spine, the discs compress and absorb the impact, helping to protect the vertebrae and spinal cord.

Vertebrae

The vertebrae are the individual bones that make up the spine. They are stacked one on top of the other and connected by ligaments and muscles. The vertebrae provide structural support for the spine and help to protect the spinal cord. Each vertebra has a hole in the center called the vertebral foramen. The spinal cord passes through the vertebral foramina of all the vertebrae.

The discs and vertebrae work together to provide the spine with a number of important functions, including:

* Support: The spine supports the weight of the head and upper body.

* Flexibility: The spine allows us to bend, twist, and move in a variety of directions.

* Protection: The spine protects the spinal cord from injury.

* Sensation: The nerves in the spinal cord carry messages from the brain to the body and from the body to the brain.

Without the discs and vertebrae, the spine would not be able to function properly. These structures are essential for our ability to move, stand, and protect our spinal cords.
