Thedemarcation of the individual cells is not sharply marked, theirboundaries being indistinctly defined. 4. The epithelium of the spiral tubule closely resembles that ofthe preceding portion, consisting of similar low columnar elementspossessing granular protoplasm but less marked striations. 198 NORMAL HISTOLOGY.

The conspicuous diminution in diameter which marks the pas-sage of the spiral tubule into the descending limb of Henles loopis accompanied by a change in the character of the lining low columnar cells are replaced by flattened, transparent plates,whose nuclei, thicker than the bodies of the cells, encroach upon thelumen of the tubule as minute spindle-shaped pro
