Simple squamous epithelium is also known as which of the following?

• A. Mesothelium
• B. Endothelium
• C. Transitional epithelium
• D. Microvillus epithelium

Answer: (A)

Simple squamous epithelium is a single, flat layer of cells designed for rapid diffusion and filtration. When this thin layer lines the serous membranes that surround body cavities, it is called mesothelium. That makes mesothelium the typical name for simple squamous epithelium in those lining surfaces. Endothelium is also a simple squamous type, but it lines blood vessels and the heart, not serous cavities. Transitional epithelium is a multilayer, stretchable type found in the urinary tract, and microvillus epithelium isn’t a separate epithelial type but refers to cells with microvilli on the apical surface.
