Out of 49 serially studied juxtaglomerular apparatuses, 6 typical variants from two normal human kidneys were reconstructed graphically. The agranular Goormaghtigh cells filled the entire space between the macula densa, the afferent and the efferent arterioles and the glomerular mesangium. The Goormaghtigh cells were always in direct contact with all the other structures. They also invariably continued into the glomerular mesangium. The distal tubule regularly showed widening in the macula densa segment and, at this level, there was considerable variation in the shape of the distal tubule. Direct contact between the macula densa and the hilar arterioles was not always present, the area of contact was usually greater with the afferent than with the efferent arteriole.
在对49个连续研究的球旁器进行观察后，从两个正常人体肾脏中重建出6种典型变体，并绘制了图形。无颗粒的球旁细胞充满了致密斑、入球小动脉、出球小动脉和肾小球系膜之间的整个空间。球旁细胞总是与所有其他结构直接接触。它们也始终延续到肾小球系膜中。远端小管在致密斑段通常会变宽，在这个层面上，远端小管的形状存在相当大的差异。致密斑与肾门小动脉之间并不总是存在直接接触，与入球小动脉的接触面积通常比与出球小动脉的更大。
