WebIn Xenopus the PCP pathway is necessary but not sufficient for polarization during CE. Polarization requires integrin α5β1-fibronectin signaling, as blocking integrin function alone results in expansion of protrusive activity all around the cell, and super-activation of integrins results in suppression of all protrusive activity . WebFrom the SA node, the depolarization wave spreads via gap junctions throughout the atria and via the internodal pathway to the AV node. Why is there a delay in the electrical impulse at the AV node? The impulse is delayed for about 0.1 s, allowing the atria to respond and complete their contraction before the ventricles contract. broad wimax キャッシュバックいつWebApr 14, 2024 · What is the interatrial pathway?

"The normal cardiac rhythm originates in the sinoatrial node, which is located in the right atrium near the superior vena cava. From there, the electrical activation spreads throughout the right atrium. There are at least four locations where the activation can pass to the left atrium. Apart from Bachmann's bundle these are the anterior interatrial septum, posterior interatrial septum, and the coronary sinus. Because it originates close to the sinoatrial node and consists of long paralle… " - Function of internodal pathway
