Esophageal hiatus
Encyclopedia
In human anatomy, the esophageal hiatus is a hole in the diaphragm through which the esophagus
passes. It is located in the right crus of the diaphragm.
It is located approximately at level of the tenth thoracic vertebra (T10).
The esophageal hiatus is situated in the muscular part of the diaphragm at the level of the tenth thoracic vertebra, and is elliptical in shape. It is placed superior, anterior, and slightly left of the aortic hiatus, and transmits the esophagus, the vagus nerve, the left inferior phrenic vessels, and some small esophageal arteries from left gastric vessels. The right crus of the diaphragm loops around forming a sling around the esophagus. Upon inspiration, this sling would constrict the esophagus, forming an anatomical sphincter that prevents stomach contents from refluxing up the esophagus when intra-abdominal pressure rises during inspiration.
Esophagus
The esophagus is an organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. During swallowing, food passes from the mouth through the pharynx into the esophagus and travels via peristalsis to the stomach...
passes. It is located in the right crus of the diaphragm.
