What is "vertebra"?

The vertebra is a fundamental body part that makes up the vertebral column, or spine. It consists of a bony structure that surrounds and protects the spinal cord. Vertebrae are stacked one on top of another to form the spinal column, allowing for flexibility, support, and protection of the spinal cord and nerves. Each vertebra has distinct features, including a central vertebral foramen, spinous processes, transverse processes, and articulating surfaces for adjacent vertebrae. The vertebrae also provide attachment points for various muscles and ligaments that contribute to spinal stability and movement.
