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 aortichiatus, 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.

Precursor System Artery Vein Nerve Lymph MeshName MeshNumber DorlandsPre h 11 DorlandsSuf 12421926 The adductor hiatus is a gap between the adductor magnus muscle and the femur that allows the passage of the femoral vessels from the anterior thigh to the posterior thigh and then the popliteal fossa . It is the termination of the adductor canal and lies about 2 inches superior to the knee . Four structures are associated with the adductor hiatus. However, only two structures enter and then leave through the hiatus namely the femoral artery and femoral vein . Those vessels become the popliteal vessels popliteal artery and popliteal vein immediately after they leave the hiatus, where they form a network of anastomoses called the genicular vessels. The genicular vessels supply the knee joint. The other two structures that are associated with the adductor hiatus are the saphenous branch of descending genicular artery and the saphenous nerve . The saphenous nerve doesn t actually leave through the adductor hiatus but penetrates superficially half way through the adductor canal . Clinical considerations A fracture of the femur just superior to the knee joint will most likely affect the adductor hiatus and may cause impairment of the blood supply to the lower leg.
