Block8/Fig.7 The microscopic structure of renal medulla.

block8_14.jpg - Fig.7 The microscopic structure of renal medulla. Thisregion contains proximal and distal thick segments, thinsegments, and collecting tubules. All of the tubules areparallel, and all are cut in cross section; thus, they presentcircular profiles. Unfortunately, the tissue is shrunk seriouslyto be difficultly identified the different parts of tubule exceptthe collecting tubules (CT). The cells forming the collectingtubules are cuboidal and the boundaries between the cellsare usually evident (*); this serves as one of the mostdependable features for the identification of collecting tubules.
