furrow formed temporarily between longitudinal rugae of the gastric mucosa along the lesser curvature during swallowing; observed radiographically and endoscopically, it is formed because of the firm attachment of the gastric mucosa to the muscular layer, which is devoid of an oblique layer at this site; said to form a passageway favored by saliva and small quantities of masticated food and other fluids as they flow from cardia to gastroduodenal junction.
