What process of a typical vertebrae forms the rounded central portion that faces anterior in the human vertebral column?

The rounded central portion of a typical vertebra that faces anteriorly in the human vertebral column is formed by the vertebral body. This structure is primarily composed of cancellous bone, which is surrounded by a layer of compact bone, providing strength and support. The vertebral body serves as a weight-bearing element and is crucial for maintaining the stability and alignment of the spine.
