The anterior articulating facets.
(That's where the joints are. What keeps them from coming apart is ligaments and muscles.)
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 ligamentum flavum is a tendon that holds your vertebrae to each other.
A disc
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
A disc of cartilage is found between each of the vertebrae.
The ribs articulate with the thoracic vertebrae. The thoracic vertebrae also articulate with each other.
The vertebrae has two major functions: to provide support and to provide protection. The vertebrae helps to provide support by forming the core structure of the body's frame. If you think about it, the vertebrae connects everything (the limbs, head) to each other. The vertebrae also provides protection for the spinal nerves. These nerves are responsible for sending/receiving motor and sensory information to the brain. If these are damaged, paralysis can occur.
Without such separation you will not have mobility of the spine. Some times the adjoining vertebrae fuse and create the problem.
The only thing that connects the left and the right (1-10) is the sternum in the middle and the vertebrae in the back. 10-12 are only connected by the vertebrae between them.

The spine , tailbone and neck(:
So the vertebrae in your spine will not grind agaist each other.
The ligamentum flavum is a tendon that holds your vertebrae to each other.
If your spine had no discs, the vertebrae would scrape very painfully against each other. This would be instantly crippling.
They are warm blooded.
Almost all the joints between vertebrae are movable. The joints between the cervical vertebrae and lumber vertebrae have fairly good movement. Between thoracic vertebrae only you have less movement. But then they do move on each other.
The device allowing two computers to communicate with each other is... a router (or modem).
