	Stratified squamous epithelium
	Simple columnar epithelium
	Transitional epithelium
	Trabecular epithelium

20 An endothelium (inner lining of vessels) is not an epithelium. Why?

	Endothelium is layer of muscle tissue
	Endothelium is of mesenchymal origin
	Endothelium is form of nerve tissue
	It's a trap! Endothelium does not exist
