The Z-line, also known as the gastroesophageal junction, is the anatomical boundary where the esophagus meets the stomach. A measurement of 38 cm from the incisor teeth typically indicates the distance from the mouth to this junction in an adult. This distance can vary among individuals and is often used in medical contexts, such as in endoscopy, to locate the Z-line for diagnostic or treatment purposes. Proper identification of the Z-line is essential for assessing conditions like gastroesophageal reflux disease (GERD) and other esophageal disorders.
