The linea semilunaris (also semilunar line or Spigelian line) is described by Adriaan van den Spiegel (°1578 †1625) described the Linea Semilunaris as the line forming and marking the transition from muscle to aponeurosis in the transversus abdominis muscle of the abdomen. It needs to be distinguished from the lateral border of the rectus ...
The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta.It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve.
An aortic sinus, also known as a sinus of Valsalva, [1] is one of the anatomic dilations of the ascending aorta, which occurs just above the aortic valve.These widenings are between the wall of the aorta and each of the three cusps of the aortic valve.
Aortography involves placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta. The procedure is known as an aortogram. The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen.
The aorta (/ eɪ ˈ ɔːr t ə / ay-OR-tə; pl.: aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries).
The hemodynamics of the aorta is an ongoing field of research in which the goal is to identify what flow patterns and subsequent forces occur within the thoracic aorta. These patterns and forces are used to identify the presence and severity of cardiovascular diseases such as aortic aneurysm and atherosclerosis . [ 1 ]
The aortic orifice (aortic opening) is a circular opening, in front and to the right of the left atrioventricular orifice, from which it is separated by the anterior cusp of the bicuspid valve.
In human anatomy, the descending aorta is part of the aorta, the largest artery in the body. The descending aorta begins at the aortic arch and runs down through the chest and abdomen . The descending aorta anatomically consists of two portions or segments, the thoracic and the abdominal aorta, in correspondence with the two great cavities of ...
