The diaphragma sellae or sellar diaphragm is a small, circular sheet of dura mater forming an (incomplete) roof over the sella turcica and covering the pituitary gland lodged therein. The diaphragma sellae forms a central opening to accommodate the passage of the pituitary stalk (infundibulum) [ 1 ] which interconnects the pituitary gland and ...

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.

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 ...
The aortic hiatus is a midline [1]: 185 opening in the posterior part of the diaphragm giving passage to the descending aorta as well as the thoracic duct, and variably the azygos and hemiazygos veins. [2] It is the lowest and most posterior of the large apertures. [citation needed]
The diaphragm typically appears as two separate, curved outlines (hemidiaphragms) on a chest X-ray due to the heart and mediastinum obscuring its central portion. When air accumulates in the mediastinum or peritoneal cavity, it outlines the diaphragm, making its central portion visible and creating the appearance of a continuous line. [4]
The sternocostal triangle (foramina of Morgagni, Larrey's space, sternocostal hiatus, etc. [1]) are small zones lying between the costal and sternal attachments of the thoracic diaphragm. No vascular elements are present within this space. [2] The borders of this space are: Medial: the lateral border of the sternal part of the diaphragm
