Verified step by step guidance

Understand the anatomy of the vertebral column: The vertebral column is divided into cervical, thoracic, lumbar, sacral, and coccygeal regions. Each region has unique features that distinguish its vertebrae.

Focus on the thoracic vertebrae: Thoracic vertebrae are located in the mid-back and are unique because they articulate with the ribs. This articulation is facilitated by specific structures called costal facets.

Define costal facets: Costal facets are small, smooth areas on the thoracic vertebrae that serve as attachment points for the ribs. These facets are located on the sides of the vertebral body and the transverse processes.

Compare the other options: Transverse foramina are unique to cervical vertebrae, not thoracic vertebrae. All vertebrae, including thoracic vertebrae, have vertebral foramina to house the spinal cord. Large, kidney-shaped vertebral bodies are characteristic of lumbar vertebrae, not thoracic vertebrae.

Conclude that the presence of costal facets for rib articulation is the feature unique to thoracic vertebrae, as it distinguishes them from cervical, lumbar, and other vertebrae.
