The pacemaker, specifically the sinoatrial (SA) node, is often referred to as the "tissue of the heart" because it is a specialized cluster of cells that initiates and regulates the heart's electrical impulses. This tissue sets the pace for heartbeats by generating electrical signals that trigger contractions in the heart muscle. As a result, it plays a crucial role in maintaining the heart's rhythm and ensuring efficient blood circulation throughout the body.
What else can I help you with?
Which is the area of specialized nervous tissue in the heart that is known as the pacemaker of the heart?
sinoatrial node
What Special tissue in right atrium that regulates heartbeat?
The sinoatrial (SA) node, also known as the pacemaker of the heart, is a special tissue located in the right atrium that acts as the natural pacemaker for the heart. It generates electrical impulses that regulate the heartbeat by initiating each heartbeat and setting the rhythm for the heart.
What is the common name for the sinoatrial node?
which of the following applies to the sinoatrial node? a)it is a mass of nerve cells b)it produces important enzymes c)it generates autorhythmic impulses to the contractthe heart d)it contains both bicuspid and tricuspid valves
What is the pacemakers function?
A pacemaker is nothing but a specialized mass of muscle tissue present in the wall of the heart. It initiates the heart beat.
Te sinoatrial is located where?
The sinoatrial node is impulse generating tissue in the (R) atrium of the heart. It is the natural pacemaker of the heart.
Sensitive tissue in the right atrium that begins the heart beat?
Buchman's Bundle
What is the internal pacemaker of the heart called?
SA node (Sinus Node)
What is considered the pacemaker of the heart?
The sinoatrial node is considered the pacemaker of the heart.
Is the pacemaker of the heart under normal circumstances is called the sinoatrial SA node?
Yes the sinoatrial node is also called the pacemaker under all circumstances
Why you call SA node as pacemaker?
The SA node normally functions as the pacemaker for the entire heart because its intrinsic rate is the fastest in the system. From the SA node, impulses spread out over the atria, causing them to contract.
What is the sa node?
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.
What is the function of the group of cells in the heart called pacemaker?
sending out signals to make the heart muscles contract.
