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.
咽食管段(PES)是一种横纹肌结构,将相对较宽的咽部与狭窄的颈段食管分隔开来。PES内存在明显的轴向和纵向不对称,以及受多种刺激和吞咽显著影响的基础静息压力。
