Which vertebral feature faces caudally in the thoracic region?

Which vertebral feature faces caudally in the thoracic region?

• A. Neural canal
• B. Transverse process
• C. Vertebral body
• D. Spinous process

Answer: (D)

In the thoracic region, the spinous processes slope downward, so they face caudally (toward the tail end). This downward orientation is a characteristic feature of thoracic vertebrae and helps explain attachment sites for muscles and ligaments as well as their overlap with the vertebra below. By contrast, the neural canal (for the spinal cord) faces posteriorly, the vertebral body faces anteriorly, and the transverse processes project laterally. So the vertebral feature that faces caudally is the spinous process.
