What is the electrical pathway of the heart?The Sinoatrial Node:The sinoatrial (SA) node is a cluster of nervous cells located in the upper right portion of the right atrium. The SA node is considered to be the

The sinoatrial (sinus) node (1) initiates an electrical impulse that flows through the right and left atria (2), making them contract. When the electrical impulse reaches the atrioventricular node (3), it is delayed slightly. The impulse then travels down the bundle of His (4), which divid...
The heart has a regulatory system, known as the intrinsic conduction system, that determines the pace of the heartbeat. Learn about the intrinsic conduction system, including the SA node, AV node, the bundle of His, bundle branches, and Purkinje fibers, and discover its role...
They mean it when they say their people are their strength; they take that to heart and their actions show it, not just their words.” Stephen Sammon Field Supervisor “I’ve been here for 14 years – and in that 14 years, I’ve gotten several awards and bonuses; the biggest bonus...
Soft electromagnetic devices have great potential in soft robotics and biomedical applications. However, existing soft-magneto-electrical devices would have limited hybrid functions and suffer from damaging stress concentrations, delamination or material
the body. Themyocardial conducting cells(1 percent of the cells) form the conduction system of the heart. Except for Purkinje cells, they are generally much smaller than the contractile cells and have few of the myofibrils or filaments needed for contraction. Their function is similar in many ...
The latter either focuses on the improvement of heart function in pathological scenarios involving dysfunction/loss of working cardiomyocytes (CMs), as is the case of acute myocardial infarction (MI) (reviewed in ref.4); or are intended to decrease the occurrence of arrhythmias and/or to restore...
The electrical charge is propagated along the membrane of the cells and in the case of nerve cells, such a system can carry the message along a defined pathway for a matter of metres, often controlling muscle movements for example. It is thought that even plants have a system of using ...
The electrical effect results in an increase in intracellular Ca2+ concentration and accelerates osteogenesis by upregulating the calmodulin signaling pathway [11]. Piezoelectric materials can mimic the piezoelectric properties of natural living bone to generate a continuous and stable charge supply in vivo...
