It is seperated by what the animals group is like Reptiles,Amphibians,Mammals,Fish,and Birds. oclusion pads of cartilage.
A vertebral disc made of a cartilage outer ring and a softer middle.
Spongy cartilage. This dries out over time, making the sponge grow smaller, which is why the elderly 'shrink.'

The ligamentum flavum is a tendon that holds your vertebrae to each other.
The anterior articulating facets. (That's where the joints are. What keeps them from coming apart is ligaments and muscles.)
A disc
The backbone is actually a collection of spinal vertebrae, each connected to each other with a fibrous disk. On the top end, the spinal vertebrae are connected to the cervical (neck) vertebrae and then to the base of the skull. On the lower end the spinal vertebrae connect to the coccyx or tailbone which is essentially 5 fused spinal vertebrae and the central part of the pelvis (hip bone). The lower portion of the spine called the lumbar region does not connect to any additional bones. In the upper portion of the spine called the thoracic region each vertebrae also connects to two ribs. Other than connecting to additional bones, there are numerous muscles, tendons, and blood vessels that also connect to the spine. Other than the structural and limited movement role of the spine, it also serves as a vital protective role for the spinal cord which leads to all the peripheral nerves of the body.
The reason there are discs of cartilage between the bones in the vertebral column is because it is to cushion the vertebrae from grinding against each other, which is what happens when arthritis/age sets in, causing the discs of cartilage to erode and letting the vertebrae grind against each other/crush the spinal cord, causing pain and/or paralysis
The ribs articulate with the thoracic vertebrae. The thoracic vertebrae also articulate with each other.
Intervertebral disc separates adjacent vertebral bodies.
Without such separation you will not have mobility of the spine. Some times the adjoining vertebrae fuse and create the problem.
Vertebrae are separted by intervertebral disks of cartilage.
The ligamentum flavum is a tendon that holds your vertebrae to each other.
So the vertebrae in your spine will not grind agaist each other.

If your spine had no discs, the vertebrae would scrape very painfully against each other. This would be instantly crippling.
The Mediastinum separates the thoracic cavity into two compartments.
