Abstract

The superstructural features of five Wistar strain male rats' sinoatrial node (SAN) at 3-mo-old were studied through transmission electron microscopy (TEM). Small fragments with the regions containing the SAN were cut off, fixed in glutaraldehyde 2.5% and processed according to the conventional technique for TEM. The morphology of the sinoatrial node of the rats is similar as found in other mammals. The SAN is an independent anatomic structure of the atrial myocardial, constituted of typical cells (nodal myocytes, transition cells and nodal cells principally) immersed in the extra cellular matrix where collagen fibers, fibroblasts and nerve predominate
