Simple squamous epithelium
This electron micrograph shows a squamous cell that forms part of the lining (serosa) of an internal body cavity. The cell has very little cytoplasm and a highly flattened nucleus, characteristic of a squamous cell. At its thinnest point, this cell is only 0.5 micron thick. Serosa 15,000x
