How many vertebrae are there in the sacral region?

The sacral region of the human spine typically consists of five vertebrae, which are known as the sacral vertebrae. These vertebrae are fused together to form the sacrum, a triangular bone located at the base of the spine, between the lumbar vertebrae and the coccyx. Understanding the structure of the sacrum is important in fields like anatomy and fitness because it plays a crucial role in supporting the pelvis and providing stability to the skeletal structure during movement. The sacral vertebrae contribute to the overall structure of the spinal column and are key in weight-bearing activities.
