The heart is made up of many cardiomyocytes, or cardiac muscle cells, that contract in response to electrical stimulation to produce the heart beat. It is vitally important for the cardiomyocytes to coordinate their contractions, so tha...
The natural pacemaker of the heart is made of cardiac muscle tissue that stimulates other cardiac muscle cells to contract. Because of its self-stimulation, cardiac muscle is considered to be autorhythmic or intrinsically controlled. The cells of cardiac muscle tissue are striated---that is, they...

The SA node responds to the body's overall need for blood and increases the heart rate when necessary, such as during exercise, emotional excitement, or illness such as fever. The SA node is sometimes called the “natural pacemaker” of the heart. ...
The heart also has an electrical system that controls the rhythm of the heartbeats. The sinoatrial node (SA node) is the natural pacemaker of the heart, and it generates electrical impulses that cause the heart to beat. The electrical impulses travel through the atria and reach the atrioventricu...
the sinus node cell, especially those which may impact pacemaking, show a day-night rhythm. The data show an all-pervasive day-night rhythm in the transcriptome of the pacemaker of the heart, the sinus node—there is a day-night rhythm in pacemaker genes and in many other systems as ...
What is the pacemaker of the heart? And why?,Questions for Paragraph 3,1. The SA and the AV initiate impulses. 2. The Purkinje fibers form a pathway for conduction of the impulse which ensures that the heart muscle 6、 cells contract in the most efficient pattern. 3. The SA node. ...
