The main function of the discs is to provide cushion and a sort of filler for the crack between vertebrae.
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.
spinal cord
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 spinal cord is found in the vertebral column, also known as the spine. This column consists of individual vertebrae that protect the spinal cord and provide structural support to the body. The spinal cord runs through the vertebral foramen of each vertebra, extending from the base of the skull down to the lower back.
Organs in the vertebral cavity include the spinal cord, which runs through the vertebral canal of the spine, along with nerve roots and blood vessels. This cavity is also home to the spinal meninges, which protect and support the spinal cord.
Your vertebral column protects the spinal cord. Vertebral column is supported by strong ligaments. Most importantly the muscle tone is there, which act on vertebral column, to protect your spinal cord.
The sides of the vertebral arch are formed by the pedicles and laminae, which extend from the vertebral body to enclose the spinal cord within the spinal canal. These structures provide protection and support for the spinal cord and nerves.

The Vertebral Cavity This answer Above is WRONG... It is the dorsal cavity! both answers are technically wrong.. the dorsal cavity holds both the cranial and spinal cavities. the cranial cavity holds the brain and the spinal cavity holds the spinal cord.
A pig's spinal cord is protected by several structures, including the vertebrae, which form the bony vertebral column, and the surrounding intervertebral discs that provide cushioning. Additionally, the spinal cord is encased in protective membranes called meninges, which include the dura mater, arachnoid mater, and pia mater. Cerebrospinal fluid also surrounds the spinal cord, providing further cushioning and protection against injury.
The spinal cord is made up of nerve tissue. This is a thick bundle of neurons that runs through the spinal canal or the vertebral column. The vertebral column is the tower of vertebral bones typically called the "spine" by laymen. The spine is in fact the amalgamation of the two. In other words the spine is the vertebral column with the nervous spinal cord running through it.
