心传导系 conduction system It is consists of the special cardiac muscles 5 parts: 窦房结 Sinoatrial node 房室结 Atrioventricular node, 房室束 Atrio-ventricular bundle 左右束支 Left and right branches 浦氏纤维 Purkinje fibers.
窦房结 sinoatrial node (SAN) *It is lies the junction between the right auricle and the sup.vena cava 房室结 atrioventricular node (AVN) *It is lies in the lower portion of the interatrial septum just above the orifice of the coronary sinus 浦氏纤维 Purkinje fibers
The vessels of the heart 心的动脉 arteries of the heart the left coronary a. the right coronary a. 心的静脉 veins of the heart the coronary sinus the ant. cardiac v. the smallest v.
冠状动脉 coronary arteries
The arteries The left coronary a. arises from the left aortic sinus 2 branches: ant.interventricular br. and circumflex br. To supply the left atrium,left ventricle,the ant. surface of the rig ht ventricle,ant. 2/3 of the interventricular septum,sometimes, su pply the SAN and AVN.
The arteries The right coronary a. arise from the right aortic sinus and runs along the right portion of the coronary groove 2 branches: post interventricular branch post branch of the left venticle To supply right atrium, right ventriclepost. 1/3 of the interventricular septum, the diaphragmatic surface of left ventricle,the SAN and AVN.
