Preferred Label : sinoatrial node;
MeSH definition : The small mass of modified cardiac muscle fibers located at the junction of the superior
vena cava (VENA CAVA, SUPERIOR) and right atrium. Contraction impulses probably start
in this node, spread over the atrium (HEART ATRIUM) and are then transmitted by the
atrioventricular bundle (BUNDLE OF HIS) to the ventricle (HEART VENTRICLE).;
