Columnar Epithelium are cells that are elongated and column-shaped. Their nuclei are usually located near the base of the cell. Some columnar epithelium cells are specialized for sensory reception, such as in the ears, nose or taste buds on your tongue. In humans, Epithelium are classified mostly as body tissue.
