Lumbar Disks
The lumbar disks are the shock absorbers of the spine, they are located between the vertebral bodies and allow soft movements, flexion and extension of the spine. They are composed by a spongy center and a a stronger outer fibrous ring or annulus that contains it.
Lateral view of the spine
A foramen is formed behind the inter vertebral disks and between the vertebrae above and below. Through these foramina exit the nerve roots that form the peripheral nerves on each side, like the sciatic nerves that run down to the legs.
