Unformatted text preview: the tubule suddenly narrows, forming the thin segment of the loop. The loop subsequently widens in the ascending limb, forming the thick segment of the loop. Cells of the nephron loop vary from simple squamous epithelium (descending limb and thin segment of ascending limb) to cuboidal and low columnar epithelium (thick segment of ascending limb) and almost entirely lack microvilli. • The final section, the distal convoluted tubule (DCT), coils within the renal cortex and empties into the collecting duct. Cells here are cuboidal with few microvilli....
