Introduction: The word ‘coronary’ (Latin word co–ro–ne) refers to a crown like arrangement of all coronary arteries in atrio ventricular sulcus  as they “encircling in manner of crown^”. Usually the heart is vascularised by the first two aortic branches called as Right and Left coronary arteries arising from anterior aortic and left posterior aortic sinuses respectively, sometime apart from the right and the left coronary arteries a third coronary artery (supernumerary artery) is also take part in the vascularisation of heart tissue significantly arises as a separate branch from anterior aortic sinus. Objective:(1)To detect prevalence of variation in number & position of coronary Ostia in aortic sinuses. (2) To detect anomalous origin of coronary arteries. Material & Method: This study was conducted on 50 formalin fixed human cadaveric hearts at Department of Anatomy Shyam shah medical college Rewa MP during 2011–12. Samples (cadaveric hearts) for this study were collected from department of Anatomy as well as from mortuary of SGMH hospital, Rewa, (M.P.), India. Result: In 16 (32 %) of the cases, two (anomalous) coronary ostia were seen in the anterior aortic sinus and in 34 (68%) of cases single normal coronary ostium was seen. In 01(2%) of cases the Lt Circumflex artery arising from Rt coronary artery was observed.Conclusion: No openings were observed in the pulmonary sinuses. Multiple ostia were mostly seen in the right anterior aortic sinus. Left Coronary ostia lies in left posterior aortic sinus mostly single in number and it located  centrally , whereas the right coronary ostia  shifted posteriorly towards the right posterior aortic sinus. And abnormal extra separate ostium lies just left to RCA ostium in anterior aortic sinus.(32%).
