Quain's elements of anatomy . s coim^nence in the labyiinth of thecortical substance by spherical dilatations enclosing like a capsule thevascular Malpighian tufts to be afterwards described. Emerging from this dilatation (fig. 566, 1), which is known as thecapside, by a narrow neck (2), the tubule is at first convoluted and wide{first convoluted tudicle), but on approaching the medullary ray itbecomes nearly straight with a slight tendency to a spiral (spiral tubuleof Schachowa, 4). At the junction of cortex and medulla the spiraltube rapidly narrows and passes straight down through the boundaryzone towards the apex of the pyramid. After a shorter or longer course,however, it loops upwards again (6) becoming enlarged in the boundaryzone (7), but somewhat smaller again above this (8, 9) where it passesagain up the medullary ray. The part of the uriniferous tube which thusdips doT^^i towards the papilla and turns upwards again is kno^vn as theloojjed tubide of Henle. On emerging from the medullary ray the tubule is. UEINIFEEOUS TUBULES. 653 characterized by great irregularity of outline {irregular tulule, 10)before again becoming convoluted {second convoluted tuhule, 11).Finally this last is connected with one of che collecting tubules of themedullary ray by a mmW junctional tulule (12), and the collecting tubes (13, Fig. 566.
