Which statement correctly contrasts viscerosomatic and somatovisceral reflexes?

• A. Viscerosomatic reflex involves a visceral problem causing a somatic symptom, while somatovisceral reflex involves a somatic problem causing a visceral symptom.
• B. Viscerosomatic reflex involves a somatic problem causing a visceral symptom, while somatovisceral reflex involves a visceral problem causing a somatic symptom.
• C. Both involve only somatic symptoms.
• D. Neither involve visceral symptoms.

Answer: (A)

Viscerosomatic and somatovisceral reflexes describe two directions of reflex influence between organs and the soma. In a viscerosomatic reflex, a visceral problem sends signals into the spinal cord that produce reflex changes in somatic tissues, such as referred muscle tension or tenderness along a spinal segment. In a somatovisceral reflex, a somatic issue stimulates pathways that alter autonomic output to an organ, leading to visceral symptoms. So, a visceral problem causing somatic symptoms and a somatic problem causing visceral symptoms is the correct contrast. The other options misstate the direction or omit the visceral involvement entirely, which doesn’t fit how these reflexes operate.
