NOTES:
This is an oil-immersion (1000 X) view of a section of the large
intestine. Individual columnar cells are clearly seen. In addition, the
goblet cells are especially prominent. At this power, it is easier to see
the microvilli of the brush border. Remember, microvilli are extensions of
cytoplasm which increase the surface area for absorption or excretion. These
are NOT the same as cilia, which provide for movement of luminal contents in
the respiratory tract and Fallopian tubes (note the complete name of this
tissue: nonciliated simple columnar epithelium).
