Anatomical terminology

The tracheoesophageal septum is formed from the tracheoesophageal folds which fuse in the midline to form a structure called tracheoesophageal septum. It divides the esophagus from the trachea. It divides the foregut tube into the laryngotracheal tube ventrally and esophagus dorsally.[2]

Developmental abnormalities can lead to a tracheoesophageal fistula.[3]
