Electricity fires from the SA node to the AV node. It then goes to the bundle of his and out the perkinji fibers.
The sinoatrial node is a part of the electrical system of the heart. The development of the sinoatrial node is from the sinus horn myocardium in fetal development.
The sinoatrial node triggers an impulse
No, it is the SAN (sinoatrial node)
In the Sinoatrial Node
The primary pacemaker of the mammalian heart is the sino-atrial node. If the SA node fails, the atrioventricular node (AV node) takes over pacemaking.
Sinoatrial Node (SA node)
Known as the "pacemaker of the heart," the sinoatrial node would most likely speed up if the body temperature were to rise.
Yes the sinoatrial node is also called the pacemaker under all circumstances
