- Goblet cell (produces mucus)
- Nucleus of a columnar cell (Note: the nuclei are at the same level in the tissue. This can help you see the single line of cells)
- Microvilli making up the “Brush Border”
- The layer of tissue to look at.
- Epithelial tissue is classified based on the shape of the cells at the apical surface and the number of layers of cells.
- This epithelial tissue consists of one layer of elongated (tall) cells.
- The nuclei are round or oval. They tend to line up at the same level within the cell, producing a line of nuclei throughout the length of the tissue.
- Some of the cells have cilia at their apical surface, some have microvilli.
- Sometimes goblet cells (which are mucus secreting cells shaped like goblets) are dispersed throughout the cellular layer.
- Absorption of nutrients. The Microvilli increase the surface area for increased absorption.
- Secretion of enzymes.
- Digestive tract: stomach, intestines, gallbladder
- Uterine tubes
- Collecting ducts of kidneys
