Abstract

The topography and arterial distribution of the sinus node in 4 hearts of deers (Mazama americana) were studied. This structure is located at the sulcus terminalis and dihedron caval-atrial angle. The sinus node is nourished by the ramus proximalis atrii dextri in 2 hearts (50.0%); by the ramus intermedius atrii dextri in 1 case (25.0%); by the ramus proximalis atrii sinistri and ramus distalis atrii dextri in 1 piece (25.0%).
