Precursor tracheoesophageal folds | ||
The tracheoesophageal septum is formed from the tracheoesophageal folds or ridges which fuse in the midline. It divides the esophagus from the trachea. It divides the foregut tube into the laryngotracheal tube ventrally and esophagus dorsally.
Developmental abnormalities can lead to a tracheoesophageal fistula.
