    The crus of diaphragm (pl.: crura), refers to one of two tendinous structures that extends below the diaphragm to the vertebral column. There is a right crus and a left crus, which together form a tether for muscular contraction. They take their name from their leg-shaped appearance – crus meaning leg in Latin.

  3. Esophageal hiatus - Wikipedia

    en.wikipedia.org/wiki/Esophageal_hiatus

    The esophageal hiatus is an oval opening [1] in (sources differ) the right crus of the diaphragm [1] /left crus of the diaphragm, with fibres of the right crus looping around the hiatus to form a sling (upon inspiration, this sling would constrict the esophagus, forming a functional (not anatomical) sphincter that prevents gastric contents from refluxing up the esophagus when intra-abdominal ...

  4. Thoracic diaphragm - Wikipedia

    en.wikipedia.org/wiki/Thoracic_diaphragm

    The esophageal hiatus is situated in the posterior part of the diaphragm, located slightly left of the west central tendon through the muscular sling of the right crus of the diaphragm. It contains the esophagus, and anterior and posterior vagal trunks, [7] left gastric artery and veins, and lymphatics. [8] aortic hiatus: T12

  5. Median arcuate ligament - Wikipedia

    en.wikipedia.org/wiki/Median_arcuate_ligament

    The median arcuate ligament is formed by the right and left crura of the diaphragm. [1] The crura connect to form an arch, behind which is the aortic hiatus , through which pass the aorta , the azygos vein , and the thoracic duct .

  6. Azygos vein - Wikipedia

    en.wikipedia.org/wiki/Azygos_vein

    The azygos vein transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava.. It is formed by the union of the ascending lumbar veins with the right subcostal veins at the level of the 12th thoracic vertebra, ascending to the right of the descending aorta and thoracic duct, passing behind the right crus of diaphragm, anterior to the vertebral ...

  7. Suspensory muscle of duodenum - Wikipedia

    en.wikipedia.org/wiki/Suspensory_muscle_of_duodenum

    The duodenum and the jejunum are the first and second parts of the small intestine, respectively.The suspensory muscle of the duodenum marks their formal division. [2] The suspensory muscle arises from the right crus of the diaphragm as it passes around the esophagus, continues as connective tissue around the stems of the celiac trunk (celiac artery) and superior mesenteric artery, passes ...

  8. Periaortic lymph nodes - Wikipedia

    en.wikipedia.org/wiki/Periaortic_lymph_nodes

    The lateral group nodes are located adjacent to the aorta, anterior to the spine, extending laterally to the edge of the psoas major muscles, and superiorly to the crura of the diaphragm. The retroaortic group are sometimes included in the paraaortic group due to their position (which is also lateral) and the same pattern of lymphatic drainage.

  9. Aortic hiatus - Wikipedia

    en.wikipedia.org/wiki/Aortic_hiatus

    The aorta is situated on the left, the thoracic duct in the middle, and the azygos vein on the right. [1]: 185 The hemiazygos vein may pass through the aortic hiatus [2] or may pass through the diaphragm independently through its own foramen in the left crus.
