Thoracic vertebrae are attached to a pair of ribs
All ribs are attached in the back to the thoracic vertebrae.
The ribs articulate with the thoracic vertebrae. The thoracic vertebrae also articulate with each other.
Without such separation you will not have mobility of the spine. Some times the adjoining vertebrae fuse and create the problem.
The cervical vertebrae do not have ribs attached.
The cervical and lumbar vertebrae do not articulate with the ribs. The thoracic vertebrae are the only ones that articulate with the ribs.
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.
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.
what animal is attached to each other if u seperate them they well die
If your spine had no discs, the vertebrae would scrape very painfully against each other. This would be instantly crippling.
All ribs articulate posteriorly with their corresponding vertebrae.
