Appendix posterior point is located at which vertebral level and side?

• A. T9 Transverse Process (left)
• B. L1 Transverse Process
• C. T11 Transverse Process (right)
• D. T12 Transverse Process

Answer: (C)

Chapman reflex points reflect viscerosomatic reflexes, and posterior points line up with the spinal level that corresponds to the organ’s sympathetic innervation. The appendix is a midgut structure and its posterior Chapman point is on the right side at the transverse process of the eleventh thoracic vertebra. That location—right, at T11—matches the typical sympathetic innervation pattern and the anatomical relationship of the appendix to theT11 region, which is why it’s the correct choice. Locations on the left side or at other levels do not correspond to the appendix’s posterior reflex point.
