title: [The pharyngoesophageal segment].
abstract: The pharyngoesophageal segment (PES) is a striated muscular structure separating the relatively wide pharynx from the narrow cervical esophagus. There is a substantial axial and longitudinal asymmetry within the PES, as well as basal resting pressure that is substantially influenced by a variety of stimuli as well as deglutition.
