The sacral region is the lower part of the spine, located between the lumbar region and the coccyx. It consists of five fused vertebrae, forming a triangular shape that connects the spine to the pelvis. This area plays a crucial role in supporting the weight of the upper body and providing stability during movement. The sacral region is also significant for its role in the nervous system. It houses the sacral plexus, a network of nerves that innervates the lower limbs and pelvic organs. This region is important for functions such as walking, sitting, and bladder control.
