Which nerves pass through the esophageal opening?

• A. Anterior Vagus Nerves
• B. Anterior & Posterior Vagus Nerves
• C. Phrenic Nerves
• D. Glossopharyngeal Nerves

Answer: (B)

The esophageal opening in the diaphragm transmits the vagal trunks, not the phrenic or glossopharyngeal nerves. As the vagus nerves descend into the abdomen, they form two trunks at or near the hiatus: an anterior trunk and a posterior trunk. These two trunks carry parasympathetic fibers to the foregut organs. The phrenic nerves run with the diaphragm but do not pass through the esophageal hiatus, and the glossopharyngeal nerves enter the skull via the jugular foramen, not through this opening. Therefore, the nerves that pass through the esophageal opening are the anterior and posterior vagal trunks.
