Which abdominal organ is reflected by the Chapman reflex at the lateral humerus?

1. Gallbladder

2. Spleen

3. Eye pathology

4. Bladder

The correct answer is: Eye pathology

The Chapman reflexes are specific somatic manifestations that correlate with visceral conditions, often referred to in osteopathic medicine. In this context, the lateral aspect of the humerus corresponds to certain organ systems. The correct answer relates to the phenomenon where abnormalities in the organ can cause referential tenderness in specific regions of the body. The Chapman reflex for eye pathology is associated with a sensory point located at the lateral aspect of the humerus, demonstrating the connection between specific organ dysfunctions and areas of somatic tenderness. This connection is used clinically to help identify issues with organs based on palpation of these reflex points. Understanding the Chapman reflex points helps osteopathic physicians in diagnosing and treating organ-related conditions through somatic manipulation.
