There is a structure called intervertebral disc that serves as a pad between two vertebral bones of spine. The interior of this structure is called nucleus pulposus, a gel-like structure containing about 80-90% intercellular water. Nucleus pulposus is surrounded by a highly elastic solid structure called annulus fibrosus. If annulus fibrous is torn or worn causing the gel-like soft structure flow out, into the spinal canal, this medical condition is then called as spinal disk.
