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

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

Answer: (A)

The concept being tested is where the posterior Chapman point for the appendix is located. In osteopathic palpation, the appendix is mapped to a right-sided posterior tender point around the T11 level, specifically at the transverse process region. This right-sided location reflects the appendix’s anatomic position in theRQ and the standard Chapman point map, which pairs the appendix with the right paraspinal area at T11. Therefore, the correct location is the right side at the T11 transverse process. Placing the point at any other level or on the left fails to correspond to the appendix’s posterior Chapman point.
