NO! it is the SA Node..

sinoatrial node, right and left bundle branches, atrioventricular node, atrioventricular bundle, ventricular walls.

The atrioventricular (AV) node is located in the inferior portion of the interatrial septum near the opening of the coronary sinus.

The Atrioventricular (AV) node is located in the inferior portion of the interatrial septum. It is a specialized cluster of cells that conducts electrical signals from the atria to the ventricles, helping to regulate the heartbeat.

If the SA node fails to fire the atrioventricular node should take over.

atrioventricular node (AV node)

The rhythmic sequence of contractions is coordinated by the sinoatrial (SA) and atrioventricular (AV) nodes.

The atrioventricular node is a part of electrical control system of the heart that co-ordinates heart rate.

The heart beats regularly because it has it's own pacemaker. The pacemaker is a small region of muscle called the sinoatrial, or SA, node. It is in the upper back wall of the right atrium. The node triggers an impulse that causes both atrium to contract. Very quickly, the impulse reaches the atrioventricular, or AV, node at the bottom of the right atrium. Immediately, the atrioventricular node triggers an impulse that causes both ventricles to contract.

Atrioventricular (AV) node

The nodes in the heart control the hearts electrical system. The nodes are known as the sinoatrial node and the atrioventricular node.

Usually in patients with a pacemaker, it happens in the atrioventricular 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.

The atrioventricular (AV) node which is located in the right atrium. From there is travels down the septum, also called the atrioventricular bundle, and then spreads to all parts of the ventricles via the Purkinje fibers.

In a normally functioning heart, the SA (sinoatrial) node is the pacemaker of the heart, but if it is nonfunctional then the AV (atrioventricular) node would take over. If it isn't working either then the Bundle of His can trigger contractions, and if it isn't working the Perkinje fibers can trigger contractions. Each progressive one has a slower intrinsic heart rate.

Human heart is myogenic in nature. It consists of sinoatrial node in the right atrium below the endodermis. this node initiates the electrical impulses in heart. As it is initiator it is also called pacemaker of heart. The atrioventricular node gathers the impulses and transmits them to the purkinje fibres via. bundle of his-tawara. As atrioventricular node collects all the impulses it is also called pacesetter of heart.

The sinoatrial node and the atrioventricular node controls the Cardiac Cycle- The Sinoatrial node is often called the Pace maker.

The sinoatrial node is located in the wall of the right atrium. The Sinoatrial node emits a wave of electrical activity which reaches both Atria which causes them to contract, the wave of electrical activity is prevented from reaching the ventricles by the atrioventricular septum.

Eventually the electrical activity will reach the Atrioventricular node which is situated between the atria.The Atrioventricular node conveys this along specialised muscle fibres called The Bundle of His.The bundle of his fibres release this electrical activity at the apex of the heart which causes both ventricles to contract at the same time.

The impulse is temporarily delayed at the atrioventricular (AV) node. This delay allows the atria to contract and complete the filling of the ventricles before the impulse is transmitted to them. The delay also ensures proper coordination of the heart's contractions, promoting efficient blood flow.

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

No, the sensitive tissue in the right atrium wall that begins the heartbeat is called the sinoatrial (SA) node, not the atrioventricular (AV) node. The SA node is often referred to as the heart's natural pacemaker as it initiates the electrical impulses responsible for coordinating the heartbeat. The AV node is located in the septum between the atria and ventricles and serves to delay the impulse to allow the atria to fully contract before the ventricles do.

The bundle of His, also known as the atrioventricular bundle, is the structure of the conduction system that helps to coordinate the contraction of the ventricles. It extends from the atrioventricular node and transmits electrical impulses to the Purkinje fibers, which then cause the ventricles to contract simultaneously.

Increased firing of the sinoatrial node (SA) and conduction through the atrioventricular node (AV) of the heart, because the actions of the vagus nerve are opposed/blocked.

The point in the Purkinje system where the impulse is temporarily delayed is at the atrioventricular (AV) node. This delay allows the atria to fully contract and pump blood into the ventricles before the impulse is transmitted to the ventricles, ensuring efficient blood flow through the heart.

In a normal heart, the electrical impulse resulting in depolarization and contraction of the cardiac muscle originates in the sinoatrial (SA) node and propagates through the atria to the atrioventricular (AV) node before moving on to the ventricles.

When the electrical impulse for muscle contraction is generated, it travels throughout the muscle of each atrium, causing atrial contraction. the impulse then travels to the atrioventricular (AV) node.

according to Medical Assisting- administrative and clinical procedures with anatomy and physiology.

The atrioventricular node is the site of heart excitation. It electrically connects and coordinates the atrial and ventricular chambers at the top of the heart.

The pacemaker of the entire myocardium is the: a) Atrioventricular junction b) bundle of his c) Purkinje fibers d) Sinoatrial node

Yes, the Purkinje fibers branch from the atrioventricular node down through the interventricular septum and traven through the walls of the heart. A branch leaves the wall and travels through/with the moderator band.

The AV (atrioventricular node).  Electrical conduction is slowed down at this node, and half the time of each action potential is spent on getting the signal through the AV node.  This delay is to allow the ventricles to fill completely with blood before they get the signal to contract.

The sinoatrial (SA) node is located in the right atrium and serves as the heart's natural pacemaker, initiating each heartbeat. The atrioventricular (AV) node is located between the atria and ventricles, aiding in the coordination of electrical signals and delaying impulses before transmitting them to the ventricles.

The structure that carries the heart's electrical impulse into the ventricles is called the bundle of His. It is a collection of specialized muscle fibers located in the walls of the heart's chambers that conducts the electrical signal from the atrioventricular node to the ventricles, initiating their contraction.

The myocardial muscle (aka myocardium or cardiac muscle) is what contracts to keep your blood flowing, but its actually the cardiac myocytes (muscle cells), which are called "autorhythmic", that keep it beating. Specifically, the SA node (sinoatrial node) is a patch of myocytes that is the pacemaker that initiates each heartbeat and determines the heart rate. Signals from the SA spread to the atrioventricular node (AV node) which acts as a gate to pass that charge to the atrioventricular bundle (AV bundle), which then disperses the charge to the purkinje fibers, which distribute the electrical charge to all mycocytes in the ventricles.

The Cardiac Control Centre (CCC) is located in the brain, and controls the impulses created in the heart by the Synal Atrial node (SA node) as well as the impulses in the Atrioventricular node (AV node). The 'CCC' therefore controls systole in the atria and ventricles, and consequently heart rate is heightened or reduced based on the commands the Cardiac Control Centre gives out.

The elements of the intrinsic conduction system in the heart in order are the sinoatrial (SA) node, the atrioventricular (AV) node, the bundle of His, the bundle branches, and the Purkinje fibers. The SA node (pacemaker) generates electrical impulses, the AV node delays the signal, the bundle of His and bundle branches conduct the signal through the ventricles, and the Purkinje fibers distribute the signal throughout the ventricular muscle.

The sinoatrial (SA) node, located in the right atrium, is the main pacemaker of the heart. It generates electrical impulses that spread through the atria, causing them to contract. These impulses then travel to the atrioventricular (AV) node and then the bundle of His, leading to ventricular contraction and the heartbeat.

The bundle of His is the component of the conduction system located between the ventricles. It is responsible for transmitting electrical signals from the atrioventricular node to the Purkinje fibers in the ventricles.

The brain stem is what controls the heart rate. The heartbeat is triggered by electrical impulses that travel down through the SA (sinoatrial) node, AV (atrioventricular) node, and the His-Purkinje Network.

The atrioventricular node and the bundle of HIS are the electrical conduction link between the atria and the ventricles.

Atria and ventricles would contract at about the same time.

The plexus of Rashkow is located in the heart. It is a collection of nerve fibers within the atrioventricular (AV) node, which plays a role in regulating the electrical conduction in the heart.

An impulse travels through the heart by moving from the sinoatrial (SA) node to the atrioventricular (AV) node, then through the bundle of His, the bundle branches, and finally to the Purkinje fibers. This pathway coordinates the contraction of the heart muscle, leading to a synchronized heartbeat.

The AV junction consists of the atrioventricular node (AV node) and the His-Purkinje system. The AV node is located near the tricuspid valve and acts as a gateway for electrical signals from the atria to the ventricles. The His-Purkinje system helps to rapidly transmit these signals to the ventricles, allowing for coordinated contraction of the heart chambers.

The AV node is located in the lower part of the right atrium of the heart, near the septum. It functions as part of the heart's electrical conduction system, helping to regulate the timing of the heart's contractions. The AV node receives electrical impulses from the SA node and transmits them to the ventricles to coordinate the heart's pumping action.

The "nodes" in the heart are the sinoatrial, or SA, node, which is found in the R atrium and is considered the primary pacemaker of the heart. The atrioventricular node, or AV node, is located in the right atrium just above the medial leaflet of the tricuspid valve. It allows for the electrical impulses generated in the atrium to be transmitted to the ventricles and to cause ventricular contraction.

The cardiac conduction system consists of the sinoatrial (SA) node, atrioventricular (AV) node, bundle of His, right and left bundle branches, and Purkinje fibers. These components work together to coordinate the electrical impulses that regulate the heartbeat.

The pacemaker of the heart is the sinoatrial (SA) node, which is located in the upper right atrium, just below the entrance of the superior vena cava. The SA node is responsible for setting the heart rate for the heart.
