Which of the following statements is true regarding the sacrum?

It consists of five fused vertebrae.
It supports the head directly.
It is located above the lumbar spine.
It articulates with the vertebrae of the neck.

The correct answer is: It consists of five fused vertebrae.

The statement that the sacrum consists of five fused vertebrae is accurate and reflects a critical anatomical detail. The sacrum forms the posterior portion of the pelvic cavity and typically consists of five sacral vertebrae that are fused together into a single triangular-shaped bone in adults. This fusion provides stability and strength to the pelvis as it serves as a base for the vertebral column. Understanding the structure and function of the sacrum is important, as it connects the spine to the hips and plays a significant role in weight distribution when standing and walking. It also houses the sacral nerve roots, contributing to the nervous system's functionality in the lower body.
