• Luminal surface structures of human and dog endolymphatic sacs were observed with the scanning electron microscope. Based on morphological views, we recognized three portions in both human and dog endolymphatic sacs as described in previous investigations. Those were the proximal, intermediate (rugose) and distal portions. The intermediate portion where light and dark cells were recognized, was found to be the most active and highly differentiated part.The morphological structure seemed to be more complicated in this portion because in addition to these light and dark cells, flat duct type cells and fusiform cells were also seen. Additionally, vesicles which appeared to be secreted were seen in this intermediate portion.Both the distal and the proximal portions were lined with flat type cells. Among these flat type cells groups of dome like cells were seen in the endolymphatic sacs of humans. On the other hand, centrioles were observed on some flat cells in the dog endolymphatic sac.
