The coronary artery is a muscular structures capable of rapid varianomic nerves and vasoctive substances relused by the vascular endothelium and platelets. (77)
The right and left coronary arteries are the first branches from the aorta as there are almost three aortic sinuses and only two coronary arteries, these permits the sinuses along with their arteries valve leaflet to be nominated as right coronary and left coronary,respectively.The third sinus , which does not carry a coronary artery,is then termed the non – coronary sinus. The coronary arteries always arise within the sinuses of valsalva , below the aortic bar, the right coronary artery enters the atrioventricular grave and encircle the tricuspid orifice giving a trial branches superiority and ventricular branches inferiority.The left coronary artery, entering the lateral margin of the transverse sinus beneath the left a trial appendage, has a very short course, it is divided into the anterior inter ventricular and circumflex arteries.
