cardiac anatomycardiac conduction systemcardiac cycleco‐dominant circulationcoronary circulationThe cardiac conduction system lies beneath the endocardium within the myocardium and consists of specialised myocytes responsible for generating and transmitting an impulse across the heart. It controls heart rate ...
Conduction System of the Heart If embryonic heart cells are separated into a Petri dish and kept alive, each is capable of generating its own electrical impulse followed by contraction. When two independently beating embryonic cardiac muscle cells are placed together, the cell with the higher inhere...
The intrinsic conduction system of the heart is comprised of several specialized subpopulations of cells that either spontaneously generate electrical acti... Laske, Timothy G.,Iaizzo, Paul A. - Anatomy and Physiology Overview of the Cardiac Conduction System 被引量: 0发表: 2024年 Development of ...
Physiology of the Cardiac Conduction SystemThe diagnosis and management of cardiac arrhythmias has progressed rapidly as a science. Advances in the ability to diagnose and either suppress or eliminate arrhythmic substrates has taken an exponential trajectory. Whether utilizing three-dimensional electro-...
Cardiac muscle tissue is only found in the heart. Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. Similar to skeletal muscle, cardiac muscle is striated and organized into sarcomeres, possessing the same banding organization as skeletal muscle ...

system, unlike the left side, which supplies the systemic circulation and requires more myocardial tissue to generate higher pressure. Blood returns from the lungs through the 4 pulmonary veins into the left atrium, flows through the mitral valve into the left ventricle, and then passes through ...
The autonomic cardiac nervous system (ACNS) is responsible for important cardiac functions, such as heart pulse, heart contraction, heart pressure, and cardiac pain delivery. Therefore, many studies of the ACNS from viewpoints of the clinical anatomy and functional analyses using experimental animals...
This article will discuss each of the phases in more detail; describing the changes in pressure and the heart valves’ actions in the cardiac cycle. You can read more on the anatomy of the cardiac valves here. Filling Phase The ventricles are filled with blood in two stages – diastole (...
We determined how these myocytes are distributed across the heart by utilising advanced single-cell and spatial transcriptomic analyses, genetic fate mapping and molecular imaging with computational reconstruction. We demonstrated that they form the key functional components of the cardiac conduction system ...
