A Zenker diverticulum is found in proximity to which structure?

Explanation:
Zenker diverticulum forms in the cervical pharynx just above the cricopharyngeus muscle, at Killian’s dehiscence, which places it right next to the upper esophageal sphincter. This location means the pouch arises at the pharyngoesophageal junction and protrudes posteriorly, explaining its proximity to the UES. It is not located in the nasopharynx, stomach, or thoracic esophagus.
