The discs in your back help support you spine. Without the discs your spine would literally fall apart.
Spinal discs are soft but tough pads of tissue between the vertebrae, and provide the spinal column with flexibility.
Spinal desiccation is the process by which the discs of the spinal column die or develop atrophy. This causes considerable discomfort due to the reduced elasticity and direct contact between the discs.
In human anatomy, the vertebral column (backbone or spine) is a column of 24 vertebrae, the sacrum, intervertebral discs, and the coccyx situated in the dorsal aspect of the torso, separated by spinal discs. It houses the spinal cord in its spinal canal.
The main function of the discs is to provide cushion and a sort of filler for the crack between vertebrae.
The presence of the discs and the S-shaped or springlike construction of the vertebral column prevent shock to the head in walking and running and provide flexibility to the body trunk.
The spinal column is a bony encasement made of movable discs, which protect the spinal cord but allow for movement. If the spine is bent too sharply the spinal column or spinal cord can be injured. http://www.brainandspinalcord.org/spinal-cord-injuries/index.html
because during the growth of human beings the vertebral column outgrows the spinal chord. that's why we don't find the spinal cord starting from lower lumbar region where lumbar puncture is done.
All animals with a spinal chord have a spinal column to protect it. The spinal column is often referred to as the "back bone", so only vertebrates have one.
Cartilage disks in the vertebral column provide flexibility and shock absorbing qualities to the spine. These disks become less elastic with age.
The spinal column decreases in overall height due to a softening and flattening of the vertebral bones, as well as a loss of fluid contained in the discs between the bones.
You can get herniated discs.
There are 7 bones that are formed at the top of the spinal column.
