Verified step by step guidance

Understand the anatomy of the vertebral column: The vertebral column, also known as the spine, is a series of interconnected bones (vertebrae) that provide structural support and protect the spinal cord. It forms the central axis of the skeleton.

Identify the regions of the vertebral column: The vertebral column is divided into five regions—cervical, thoracic, lumbar, sacral, and coccygeal. These regions extend from the base of the skull to the pelvis.

Clarify the anatomical landmarks: The base of the skull is where the cervical vertebrae begin, and the pelvis is where the sacral vertebrae connect. This defines the vertical axis of the skeleton formed by the vertebral column.

Compare the options provided: Evaluate each option based on anatomical accuracy. For example, the clavicle is part of the shoulder girdle and not connected to the vertebral column, while the sternum is part of the rib cage and does not extend to the coccyx.

Conclude with the correct answer: The vertebral column extends from the base of the skull to the pelvis, making this the anatomically correct description of its vertical axis.
