Anterior Anterior longitudinal longitudinal sulcussulcus
You can find the anterior side of the heart by finding the auricle that you can see completely; it is the left auricle. The anterior longitudinal sulcus is on that side and the coronary sinus is on the posterior side.

Pectinate Muscles are parallel ridges in the walls of the atria of the heart. They resemble the teeth of the comb.
