1) The sulcus that separates the atria from the ventricles is the atrioventricular sulcus. 2) Neighboring cardiac muscle cells in the walls of heart chambers have specialized cell-cell contacts that electrically and mechanically link the cells together, permitting the immediate passage of muscle impulses. These cell contacts are called intercalated discs. 3) Unidirectional flow in the heart is ensured because the heart contains valves that prevent backflow. 4) Check all that are a function of the pericardium. Check All That Apply: Prevent the heart from bouncing in the thoracic cavity, Prevent the heart from overfilling with blood, Aid the heart in the strength of contractions, Create a frictionless environment through the production of serous fluid. 5) The fibers that extend through the walls of the ventricles and allow the rapid, immediate spread of the impulse throughout the ventricular myocardium are called Purkinje fibers. 6) The fibers that extend through the walls of the ventricles and allow the rapid, immediate spread of the impulse throughout the ventricular myocardium are called Purkinje fibers. 7) The valve that prevents backflow of blood into the right ventricle is the tricuspid valve. 8) True or False. The less extensive distribution of T-tubules contributes to the more delayed onset and prolonged contraction of cardiac muscle tissue compared to skeletal muscle tissue.
