Stomach (Acidity) Posterior Point is located at which transverse process?

• A. T5 Transverse Process (Left)
• B. T3 Transverse Process
• C. T4 Transverse Process
• D. T2 Transverse Process

Answer: (A)

Think of Chapman reflexes as visceral checkpoints that map to the spine. The posterior points reflect the sympathetic supply to an organ, so finding the correct transverse process helps us address autonomic input to that organ.

The stomach’s sympathetic innervation mainly comes from the greater splanchnic nerves, which originate around the mid-thoracic levels. The classic posterior Chapman point for the stomach is on the left side at the transverse process level corresponding to the mid-thoracic region, specifically the left mid-thoracic transverse process. This left-sided location aligns with the stomach’s left-sided anatomy and its sympathetic input pattern.

If you encounter tenderness there, treating that point with appropriate OMM techniques can help modulate visceral sympathetic tone and potentially improve gastric function. Other transverse process levels or right-sided points correspond to different visceral patterns, so they don’t fit the stomach’s posterior Chapman point.
