These cells carry electrical energy through the heart in a predictable pattern, stimulating the different parts of the heart to contract in a regular rhythm. This network is called the intrinsic cardiac conduction system. Answer and Expla...

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 ...
They act also to conduct impulses throughout the heart, in a rapid and coordinated fashion1. The main components of the cardiac conduction system are the sinus node of the right atrium, which is the primary pacemaker; the atrioventricular conduction axis, which normally forms the only pathway ...
Pacemaker of heart is …… . View Solution The pacemaker of human heart is View Solution Assertion : Though AV node generates impulses, it is still not called as the pacemaker of heart. Reason : The rythmicity of impulse production is not highest in AV node in the neuromuscular conduction...
muscle tissue in the posterior portion of the right atrium, where an electrical impulse originates. This is the sinoatrial node (SA node), or pacemaker of the heart. The current of electricity generated by the pacemaker causes the ...
The "pacemaker" of the heart is the A. SA node. B. AV node. C. AV septum. D. ventricle. Blood Flow in the Heart: The heart is the major organ of the cardiovascular system and receives and delivers blood to and from all parts of the body. All deo...
