The bone at the base of the human spine is called the sacrum. The sacrum is a large triangular bone located at the base of the spine, between the two hip bones. It consists of five fused vertebrae and plays a crucial role in connecting the spine to the pelvis.

The sacrum serves as a strong foundation for the spine and pelvis, providing stability and support for the entire upper body. It also helps to transfer the weight of the body to the lower limbs and pelvis, allowing for movement and flexibility.

One of the key functions of the sacrum is to protect the delicate spinal cord that runs through the spinal canal. It also provides attachment points for various muscles, ligaments, and tendons that help to support the spine and pelvis.

Issues with the sacrum can lead to a range of problems, including lower back pain, sciatica, and problems with mobility. It is important to maintain good posture, engage in regular exercise, and seek medical attention if you experience any discomfort or pain in the sacral area.
