The term "vertebral" refers to anything related to the vertebrae, which are the small bones that make up the spine. The spine is a crucial part of the human skeleton, providing support and protecting the spinal cord, which is essential for transmitting signals between the brain and the rest of the body. Each vertebra is separated by intervertebral discs that act as cushions, allowing for flexibility and movement. In the context of anatomy, the vertebral column is divided into several regions: cervical, thoracic, lumbar, sacral, and coccygeal. Each region has a specific number of vertebrae, contributing to the overall structure and function of the spine. Proper alignment and health of the vertebral column are vital for maintaining good posture and preventing back pain.
