The tissue that forms an electrical block between the atria and ventricles is the atrioventricular (AV) node and the surrounding fibrous tissue known as the cardiac skeleton. The AV node receives electrical signals from the atria and delays them before transmitting to the ventricles, allowing for coordinated heart contractions. The cardiac skeleton provides structural support and insulation, preventing direct electrical conduction between the atria and ventricles, ensuring that the heart beats in a controlled manner.
The electrical impulse reaches all the muscle tissue in the ventricles, and the ventricles contract. This electrical conduction pattern occurs approx. every 0.8 seconds.
It is the atrioventricular bundle or bundle of His
TRUE
Yes, the heart has a fibrous skeleton, which is a dense connective tissue structure that provides support and stability to the heart. Its primary functions include anchoring the heart valves, maintaining the shape of the heart, and serving as an electrical insulator that helps regulate the conduction of electrical impulses between the atria and ventricles. This organization ensures proper timing and coordination of heart contractions.
Nerve tissue is specialized to conduct electrical signals (impulses) from one part of the body to another. Nerve cells, or neurons, have unique properties that allow them to transmit these signals through a combination of electrical and chemical processes.
The electrical impulse reaches all the muscle tissue in the ventricles, and the ventricles contract. This electrical conduction pattern occurs approx. every 0.8 seconds.

Cerebrospinal fluid (CSF) is primarily formed in the ventricles of the brain, specifically in the choroid plexus, which is a tissue structure that lines the ventricles. The choroid plexus produces CSF by filtering blood plasma and secreting it into the ventricles, where it circulates around the brain and spinal cord providing buoyancy and protection.
The small bundle of nerve tissue you are referring to is the Purkinje fibers, part of the heart's conduction system. These fibers conduct electrical impulses from the atrioventricular (AV) node to the ventricles, leading to their contraction. This process ensures coordinated and efficient pumping of blood throughout the body. The Purkinje fibers play a crucial role in maintaining the heart's rhythm and overall function.
