In this case, there is a rapid depolarization, followed by a plateau phase and then repolarization. This phenomenon accounts for the long refractory periods required for the cardiac muscle cells to pump blood effectively before they are capable of firing for a second time. These cardiac myocytes normally do not initiate their own electrical potential but rather
wait for an impulse to reach them. Recommended textbook solutions

Hole's Human Anatomy and Physiology13th EditionDavid N. Shier, Jackie L. Butler, Ricki Lewis 1,402 solutions What is the correct order of the conduction system of the heart?The SA node starts the sequence by causing the atrial muscles to contract. That's why doctors sometimes call it the anatomical pacemaker. Next, 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.
What is the correct order of conduction through the heart's conduction system quizlet?Name the cardiac conduction cycle events in order: The electrical impulse is initiated at the SA node. The impulse passes to the AV node, which is passed on the the AV bundle. The impulse is transmitted to the Purkinje fibers and the ventricles contract.
What are the 5 steps to the conduction system of the heart?This pathway is made up of 5 elements:. The sino-atrial (SA) node.. The atrio-ventricular (AV) node.. The bundle of His.. The left and right bundle branches.. The Purkinje fibres.. What are the 5 steps to the conduction system of the heart quizlet?cardiac conduction. in vertebrates the signal to trigger each heartbeat comes from the heart itself.. SA node fires. ... . Signal from SA node. ... . AV node fires. ... . Excitation spreads. ... . Parkinje fibers.. |
