The present study was conducted on 20 sheep heart ranging from 53 days to 146 days of prenatal life Histologically, Sinoatrial node formation was noticed at the base of the interatrial septum at 53 and 56 days of prenatal life. A piece of hyaline cartilage (cartilagocordis) was observed at the base of interatrial septum on the right side of aortic orifice at 98 days. Fonnation of atrioventricular node was observed at 120 days in the proximal part of the interventricular septum.
