SA node (Sinus Node)
The sinoatrial node is considered the pacemaker of the heart.
Yes the sinoatrial node is also called the pacemaker under all circumstances
The SA node is the "pacemaker" of the heart. Cells in the SA node are called "pacemaker" cells and they direct the contraction rate of the entire heart by generating action potentials.
sending out signals to make the heart muscles contract.

SA node (Sinus Node)
No, the sino-atrial node is the pacemaker of the heart. It receives signals from the heart centre in the medulla oblingata via either the parasympathetic nerve or sympathetic nerve. It the sends a signal to the right- and left artrium and then to the atrioventricular node which stimulates the right- and left ventricles to contract
The contraction of heart (cardiac) muscle in all animals with hearts is initiated by chemical impulses. The rate at which these impulses fire controls the heart rate. The cells that create these rhythmical impulses are called pacemaker cells, and they directly control the heart rate.
No, the Sinoatrial Node is known as the natural pacemaker of the heart
The SA node, the natural pacemaker of the heart, is found in the right atrium of the heart.
The sinoatrial node is known as the pacemaker of the heart.
