The sinoatrial node (SAN) is the normal pacemaker generating the regular, rhythmic contraction of the mammalian heart. Pacemaker activity of SAN cells is based on the diastolic depolarization, during which SAN cells depolarize spontaneously toward the action potential threshold. However, single SAN ...
2.A leader in a field:the fashion house that is the pacemaker.Also calledpacesetter. 3. a.A part of the body, such as the mass of muscle fibers of the sinoatrial node, that sets the pace or rhythm of physiological activity. b.Any of several usually miniaturized and surgically implanted ...
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. ●Electrical impulses leave the SA node ...
SA node is the pacemaker of the heart. It is the most important part of the nodal tissue of the heart present at the right upper portion of the right atrium that can excite itself without any stimulus. Answer and Explanation: If the SA nodes f...

Answer to: The "pacemaker" of the heart is the A. SA node. B. AV node. C. AV septum. D. ventricle. By signing up, you'll get thousands of...
Veins. These are blood vessels that take blood back to the heart; this blood lacks oxygen (oxygen-poor) and is rich in waste products that are to be excreted or removed from the body. Veins become larger and larger as they get closer to the heart. The superior vena cava is the large...
Aims Animal studies revealed that the hyperpolarization-activated pacemaker current, If, contributes to action potential (AP) generation in sinoatrial node (SAN) and significantly determines heart rate. If is becoming a novel therapy target to modulate heart rate. Yet, no studies have demonstrated t...
