Layer-by-layer preparations of interatrial septum, atrium walls and the histological study of its transverse serial sections in 84 human heart specimens revealed 6 kinds of interatrial muscle fascicles: posterior horizontal, posterior oblique-horizontal, superior horizontal, anterior horizontal (Bachmann's), Z-shaped superior (above the oval fossa) and inferior (below the oval fossa). In the oval fossa and its valve, a particular structure consisting of the transitional T-cells of the heart conducting system was detected, which contacted the muffs of the entries of all pulmonary veins by means of working myocardium muscle fascicles.
对84例人体心脏标本的房间隔、心房壁进行逐层制备，并对其横向连续切片进行组织学研究，发现了6种房间肌束：后水平肌束、后斜水平肌束、上水平肌束、前水平肌束（巴赫曼束）、Z形上肌束（卵圆窝上方）和下肌束（卵圆窝下方）。在卵圆窝及其瓣膜中，检测到一种由心脏传导系统的过渡性T细胞组成的特殊结构，该结构通过工作心肌肌束与所有肺静脉入口的套袖相接触。
