Where is the Sacrum bone located in the human body?

The Sacrum is located in the pelvis, specifically at the base of the spine. It forms the back wall of the pelvis and is comprised of five fused vertebrae, which provide structural support and stability for the skeletal system. The Sacrum connects to the pelvis via the sacroiliac joints, allowing for weight transfer between the upper body and the lower limbs. This positioning is crucial for various functions, including standing, walking, and other movements that involve the legs and hips. Understanding the location of the Sacrum is essential for recognizing its role in both anatomy and biomechanics.
