The terminal sulcus is a groove on the outer surface of the right atrium of the heart marking the transition between the sinus venarum cavarum (which has a distinct embryological origin) and the rest of the right atrium (which features pectinate muscles on its inner surface). The terminal sulcus corresponds to the position of the terminal crest on the inner surface of the right atium. The terminal sulcus (and crest) indicate the position of the sinoatrial node.^[1]
