Gall bladder: epithelium
The epithelium lining the gall bladder is simple columnar with short microvilli; its oval nuclei are located in the lower one-third of each cell. The apical cytoplasm is filled with mitochondria, which supply energy to concentrate the bile, as well as secretory granules containing mucinogen. Additional mucus is added to the bile by the larger bile ducts. 1000x
