Sinoatrial nodal artery posterior aspect of the interatrial septum. The origin of the sinoatrial node artery is not related to coronary artery dominance, which means the side (right or left) that provides the circulation to the back of the heart. In contrast, the atrioventricular nodal branch, that is the artery that brings blood to the atrioventricular node, depends on coronary artery dominance. The sinoatrial node surrounds the sinoatrial artery, which can run centrally (in 70% of individuals) or off center within the node. A left S-shaped sinoatrial artery, originating from the proximal left circumflex or LCx artery, has been described as a common
Node (networking) problem but all require instilling trust in the end node computer. Node (networking) In telecommunications networks, a node (Latin "nodus", ‘knot’) is either a redistribution point or a communication endpoint. The definition of a node depends on the network and protocol layer referred to. A physical network node is an active electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communications channel. A passive distribution point such as a distribution frame or patch panel is consequently not a node. In data communication, a physical network node may either be data
