Question

Triangular bone at the base of the spine

Answer 1

The triangular bone at the base of the spine is known as the **sacrum**. It is located between the lumbar vertebrae (lower back) and the coccyx (tailbone) and is made up of five fused vertebrae. The sacrum forms the back portion of the pelvis and plays a crucial role in supporting the upper body and connecting the spine to the hip bones. Its shape and structure help with weight-bearing and stability during activities such as walking and standing.
