The semilunar hiatus (eg, hiatus semilunaris) is a crescent-shaped [citation needed] /semicircular/ [1] curved [2] slit [2] /groove [1] upon the lateral wall of the nasal cavity [3] at the middle nasal meatus just inferior to the ethmoidal bulla. [2] It is the location of the openings for the frontal sinus, maxillary sinus, and anterior ...
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 tricuspid valve, or right atrioventricular valve, is on the right dorsal side of the mammalian heart, at the superior portion of the right ventricle.The function of the valve is to allow blood to flow from the right atrium to the right ventricle during diastole, and to close to prevent backflow (regurgitation) from the right ventricle into the right atrium during right ventricular ...
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.
The common valve spring system is satisfactory for traditional mass-produced engines that do not rev highly and are of a design that requires low maintenance. [1] At the period of initial desmodromic development, valve springs were a major limitation on engine performance because they would break from metal fatigue.
The metric equivalent flow factor (K v) is calculated using metric units: =, where [3]. K v is the flow factor (expressed in m 3 /h), Q is the flowrate (expressed in m 3 /h), SG is the specific gravity of the fluid (for water = 1),
From January 2008 to December 2012, if you bought shares in companies when Steven M. West joined the board, and sold them when he left, you would have a -27.2 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
The seminal colliculus (Latin colliculus seminalis), or verumontanum, of the prostatic urethra is a landmark distal to the entrance of the ejaculatory ducts (on both sides, corresponding vas deferens and seminal vesicle feed into corresponding ejaculatory duct).
