What is the final group of bones in the spinal column known as?

The final group of bones in the spinal column is known as the coccyx. This structure, often referred to as the tailbone, is typically composed of three to five small fused vertebrae located at the very end of the vertebral column. The coccyx serves as an attachment point for various muscles, tendons, and ligaments, as well as playing a role in supporting the pelvic organs.

Understanding the vertebral column's anatomy is crucial, as it provides structural support and protects the spinal cord. The coccyx is distinct from other sections of the spine, such as the lumbar vertebrae, sacrum, and thoracic vertebrae, which are categorized based on their position and specific functions in the spine. The lumbar vertebrae are situated in the lower back, the sacrum connects to the pelvis, and the thoracic vertebrae are located in the upper and middle back, all functioning differently compared to the coccyx.
