What is the name for the specific part of the heart which sets the rate at which the heart will beat?
The pacemaker of the heart is known as the sinoatrial (SA) node. It sets the rate at which the heart will beat without any autonomic stimulation, that is, no sympathetic or parasympathetic activity. Increases in sympathetic activity will increase the heart rate while increases in parasympathetic activity decrease heart rate. The pacemaker of the heart is known as the sinoatrial (SA) node.

How can the heart muscle work with no help from you?
The heart muscle actually beats on its' own. It has two pacemakers. One sets the pace and the second, slower one, is a back up. If you had one heart muscle cell (fiber) in a Petri dish it would beat. If you add a few more, they also will beat but not together. Only if they touch, then they will beat together.

What are the group of cells that ajust the heart beat?
The pacemaker is only used during a procedure that places an artificial pacemaker in your chest to make your heart beat regular. That is only when the person's heart is having irregular heart beats. People with regular heartbeats with no artificial pacemaker....the way that the heartbeat is regular is through The SA node (sinoatrial). It is a group of cells that is located in the right atrium and sets the pace for the heart, increasing and decreasing when it is needed.
What structure sets the pace for heart contraction?
Cardiac muscles don't contract in unison, if you listen to your heart beat you should hear two distinctive thumps (1 for the atria, 1 for the ventricles). I believe the structure you're looking for is the Sinoatrial Node (SA node) which is a bundle of nerves in the upper part of the right atrium, also known as the 'pace maker'. The electrical impulse from the node triggers a sequence of electrical events (from the SA Node to the A(trio)V(entricular) node to the Purkinje fibers) which are the cause of the beating/contracting
What is pancemaker?
SA node '' sets the pace for the heart
Why do you need structure in poetry?
It sets the tone of the poem. Structure helps the reader follow along. Finally structure helps mandate the theme and your style.
Knot of modified myocardium that sets the pace of the heart?
The knot of modified myocardium that sets the pace of the heart is the sinoatrial (SA) node. The SA node is on the wall of the right atrium.
What makes the brain tell the heart to pump blood around the body?
The brain doesn't control the heart. The heart controls itself. If you would take a single heart muscle cell, it will beat on its' own. Add another and they beat together. The heart has special muscle cells called pacemakers. The primary one is called the SA (sinoventricular) node. That sets that pace or rhythm. There is also a slower back up pacemaker called the AV (atrial ventricular) node.
