2. SACRUM The sacrum is  a shield-shaped bony structure that is located at the base of the lumbar vertebrae and that is connected to the pelvis The sacrum is a single bone comprised of five separate  vertebrae  that fuse during adulthood. It forms the foundation of the lower back and the pelvis.

3. The sacrum is a concave sphenoid bone that sits at the bottom of the spinal column. It looks like an inverted triangle: the widest part (base) is at the top, and the pointy end (apex) is at the bottom. The sides of the sacrum connect to the right and left hip ( iliac ) bones. The apex is connected to the tailbone ( coccyx ). The base is connected to the largest and lowest of the lumbar vertebrae, L5.

4. strong foundation for the formation of the pelvis. The human pelvis also needs to be wide enough to provide leverage for motion and balance, as well as to facilitate childbirth. The sacrum creates an anchor point where the spinal column can attach to the pelvis and provide stability for the body's core acts as a platform for the spinal column to rest on when sitting.
