Tracheoesophageal septum
Tracheoesophageal Septum
The Tracheoesophageal septum is a vital structure in embryology that plays a crucial role in the development of the respiratory system and the digestive system. It is formed during the fourth week of human embryogenesis and separates the foregut into the trachea and the esophagus.
Formation[edit | edit source]
The tracheoesophageal septum is formed from the tracheoesophageal folds, which are longitudinal elevations in the lateral walls of the foregut. These folds grow towards each other and eventually fuse in the midline to form the septum. This process separates the foregut into a dorsal part, which becomes the esophagus, and a ventral part, which becomes the trachea and the lung buds.
Clinical Significance[edit | edit source]
Abnormalities in the formation of the tracheoesophageal septum can lead to congenital conditions such as tracheoesophageal fistula and esophageal atresia. These conditions can cause serious complications, including difficulty swallowing (dysphagia), recurrent lung infections, and potentially life-threatening respiratory issues.
