Summary

This study looks at how the upper part of the esophagus (striated esophagus) works when people swallow. Researchers want to understand how the throat and esophagus work together. They will study healthy adults and people with swallowing problems. This is an observational study, not a treatment, and aims to gather knowledge to help future care.
