What are the individual bones called in spine?

The individual bones in the spine are called vertebrae. Each vertebra is a small, complex bone that helps to form the spinal column. The spinal column is a flexible structure that runs from the skull to the pelvis and provides support for the body. It also protects the delicate spinal cord, which carries messages between the brain and the rest of the body.

There are 33 vertebrae in the human spine, divided into five regions:

* Cervical vertebrae: There are seven cervical vertebrae, located in the neck.

* Thoracic vertebrae: There are 12 thoracic vertebrae, located in the chest.

* Lumbar vertebrae: There are five lumbar vertebrae, located in the lower back.

* Sacral vertebrae: There are five sacral vertebrae, located in the pelvis.

* Coccygeal vertebrae: There are four coccygeal vertebrae, located at the base of the spine.

Each vertebra has a unique shape and structure that allows it to fit together with the other vertebrae to form the spinal column. The vertebrae are connected to each other by ligaments and muscles, which help to keep the spine stable and flexible.
