Crus Of The Diaphragm Scientific Journals

A tendinous structure, the crus of diaphragm, extends from the diaphragm and attaches to the vertebral column. The right and the left crus (pl. crura) form a tether which helps in muscular contraction. They are called crus owing to their leg-shaped appearance (crus is Latin for leg). The crura are tendinous in structure at their origins. They later go on to blend in with the anterior longitudinal ligament of the vertebral column. The right crus is larger and longer than the left and arises from the anterior surfaces of the bodies and inter-vertebral fibro-cartilages of the upper three lumbar vertebrae. The left, however, arises from the corresponding parts of the upper two lumbar vertebrae. Their medial margins pass anteriorly and medialward to meet in the middle line. This forms an arch across the front of the aorta which is called mediam arcuate ligament. But, the arch is often poorly defined. From the aortic hiastus, the area behind the arch, originates a series of fibers of the diaphragm which converge and enter into the central tendon. Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
