Question

Referred pain from visceral peritoneum in foregut:

Answer 1

Referred pain from the visceral peritoneum in the foregut can be felt in the left shoulder and left arm. This occurs because the visceral sensory fibers from the mediastinal region enter the spinal cord at the same level as the spinal nerves from the shoulder and arm.

Step-by-step explanation:

Referred pain is the conscious perception of visceral sensation projected to a different region of the body. In the case of the foregut, referred pain from the visceral peritoneum can be felt in the left shoulder and left arm. This occurs because the visceral sensory fibers from the mediastinal region, where the heart is located, enter the spinal cord at the same level as the spinal nerves from the shoulder and arm, causing the brain to misinterpret the sensations.
