Angle of His
The angle of His is the acute angle created between the cardia at the entrance to the stomach, and the oesophagus. It forms a valve, preventing reflux of duodenal bile, enzymes and stomach acid from entering the oesophagus, where they can cause inflammation.[1] The angle is created by the collar sling fibres and the circular muscles around this (gastro-oesophagal) junction.[2] The angle of His is normally undeveloped in infancy, with the oesophagus making a vertical junction with the stomach, and as a result, reflux of stomach contents is common.[3]
