Solution:
The entire heart is made of cardiac muscles. The walls of ventricles are much thicker than that of the atria. A specialized cardiac musculature called the nodal tissue is also distributed in the heart. A patch of this tissue is present in the right upper corner of the right atrium called the sino-atrial node (SAN). SAN is also referred to as the "Pacemaker of the heart".
