The spinal vertebrae are separated by cartilage disks filled with a
gelatinous substance, that provide cushioning to the spinal column.
These disks may move out of place or rupture from trauma or strain,
especially if degenerative changes have occurred in the disk. When
the disk moves out of place nerve roots (large nerves that branch
out from the spinal cord) may become compressed resulting in
neurological symptoms, such as pain, sensory and motor changes.
