purkinje fibers
Another name for the walls of ventricles is the Purkinje fibers.
Purkinje fibers
An action-potential which then travels to the Bundle of His and then the purkinje fibers to depolarize the ventricles to cause contraction.
the purkinje fibers um no!!! wrong answer!!
Very rapid contractions or twitching of small muscle fibers in the heart often need to be stopped. A mechanism that does this is called a defibrillator. The act itself is call a defibrillation. Many times the top chambers of the heart go into fibrillation and are not as severe as the ones that occur in the bottom chambers called the ventricles. These must be stopped as quickly as possible.
false (they are located within the interventricular septum)
Ventricular contractions start in the Purkinje fibers, which are specialized muscle fibers located in the walls of the ventricles of the heart. These fibers rapidly conduct the electrical signals to synchronize the contraction of the ventricles and pump blood out of the heart.
Purkinje cells are specialized cardiac cells, whose purpose it is to spread the electrical signal from the atrioventricular (AV) node down through the right and left ventricles.
The fibers of the ventricular bundle, also known as the bundle of His, are specialized cardiac muscle fibers that conduct electrical impulses from the atrioventricular (AV) node to the Purkinje fibers in the ventricles. These fibers play a critical role in coordinating the contraction of the ventricles during the cardiac cycle, ensuring effective pumping of blood out of the heart.

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.
Purkinje Fibers actually makes the ventricles contract.
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 network found in the ventricular myocardium is known as the Purkinje fibers. These specialized cardiac muscle fibers are part of the heart's conduction system and are responsible for rapidly transmitting electrical impulses throughout the ventricles. This helps coordinate the contraction of the ventricles, ensuring efficient pumping of blood. The Purkinje fibers facilitate a synchronized contraction, allowing for effective ventricular function.
