WebThis image shows the brush border of intestinal epithelium, which features simple columnar epithelial cells with basal nuclear polarity and an apical surface with microvilli. Note the size of the microvilli relative to the cells that they cover. What is the function of the microvilli? Answer: Hide Labels WebIn the apical region, the brush border of the luminal surface is composed of long, closely packed microvilli. Most of the microvilli contain chains of vesicles and elongated mitochondria that extend to their bulbous tips (Figs. 10-12), a structural relationship suggesting active physiological processes at the luminal border of the tubule cells. havilah ravula
