What are the Fibers of the conduction system of the heart?
Fibers of the conduction system of the heart is called Purkinje fibers
What carries cardiac impulses to the myocardium?
Cardiac impulses are carried to the myocardium via specialized muscle cells called Purkinje fibers. These fibers are part of the cardiac conduction system and help to transmit electrical signals rapidly and efficiently throughout the heart muscle.
Does the ECG record the electrical stimulation of cardiac muscle by conduction system?
Yes, an ECG records the electrical activity produced by the heart as it contracts and relaxes. This includes the electrical stimulation of the cardiac muscle by the conduction system, such as the SA node, AV node, and Purkinje fibers.
What segment of the cardiac conduction system functions as the pacemaker of the heart?
Sinoatrial (SA) Node
Cardiac conduction system?
The cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract. The main components of the cardiac conduction system are the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers. The SA node (anatomical pacemaker) starts the sequence by causing the atrial muscles to contract. From there, the signal travels to the AV node, through the bundle of His, down the bundle branches, and through the Purkinje fibers, causing the ventricles to contract. This signal creates an electrical current that can be seen on a graph called an Electrocardiogram (EKG or ECG). Doctors use an EKG to monitor the cardiac conduction system's electrical activity in the heart.Reviewed ByReview Date: 05/16/2011Steven Kang, MD, Division of Cardiac Pacing and Electrophysiology, East Bay Arrhythmia, Cardiovascular Consultants Medical Group, Oakland, CA.

What is conducting system of the heart description of the components of the conducting system of the heart site and function?
The cardiac conduction system is the conducting system of the heart.
What are the three components of the neuromuscular tissue of the heart are?
The three components of the neuromuscular tissue of the heart are cardiac muscle cells (myocytes), specialized conduction system cells (such as pacemaker cells in the sinoatrial node), and the autonomic nervous system (which includes sympathetic and parasympathetic fibers). Cardiac muscle cells are responsible for the contraction of the heart, while the conduction system regulates the heartbeat. The autonomic nervous system modulates heart rate and contractility in response to physiological demands. Together, these components ensure coordinated heart function and rhythm.
What part of the conduction system of the heart wraps around in the outer walls of the ventricular?
purkinje fibers
What part of the intrinsic conduction system of the heart that directly supplies the wall of the ventricle?
Purkinje fibers

What is the part of the conduction system of the heart that wraps around in the outer walls of the ventricular is?
The part of the conduction system of the heart that wraps around the outer walls of the ventricles is the Purkinje fibers. These specialized fibers help to rapidly and efficiently transmit electrical impulses to the muscle cells of the ventricles, allowing for coordinated and synchronized contractions.
A group of conducting cells control heart muscle contraction and is known as the?
pacemaker cells
