That's Correct!
It's Wrong!
The correct answer is Sionatrial. The node that acts as the 'pacemaker' in the heart is called the sinoatrial (SA) node. It is located in the right atrium and is responsible for initiating the electrical signals that regulate the heartbeat. These signals cause the myocardium to contract and pump blood throughout the body.
