Abstract:
Observation had been made on two male adults' hearts.Under electron microscopy,it is found that the A-V node consists of three types of cells,i.e.P cells,transitional cells and Purkinje cells.Because the specimen was cut from the central part of the A-V node, therefore the general myocardial cells were not observed.One of characteristics distingui- shed from the sino-atrial node is the presence of a few Purkinje cells in the A-V node.The number of P cells is far less than S-A node,and the transitional cells are predominant.In the interstitial tissues of the A-V node,the collagenous fibers are not so much as in S-A node but a numbers of capillarie,fibroblasts,mast cells and non-medul- lated nerve fibers can be seen.
