Zenker's diverticulum originates on the posterior wall of the pharyngoesophageal segment in a midline area of weakness just above the cricopharyngeus (i.e., Killian's dehiscence), whereas Killian-Jamieson diverticula originate on the anterolateral wall of the proximal cervical esophagus in a gap just below the cricopharyngeus and lateral to the longitudinal tendon of the esophagus (i.e., the Killian-Jamieson space).

The cricopharyngeus muscle is located at the junction of the pharynx (throat) and esophagus, and is the major muscular component of what is called the upper esophageal sphincter (UES). At rest, the UES closes the passageway between the pharynx and esophagus.
