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)
pukinje fibers
Purkinje Fibers actually makes the ventricles contract.
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.
purkinje fibers
the ventricles.
Ventricles
Another name for the walls of ventricles is the Purkinje fibers.
Repolarization of ventricular muscle fibers.
Which fibre? Plant fibers, such as cotton or paper are poor conductors. Glass fibers are non-conductive. Metal fibers conduct very well.
Purkinje fibers
Sinoatrial (SA) Node or "Pacemaker"
