Epithelial cells are the building blocks of epithelial tissue. Like every other cell, they are surrounded by cellular membranes. Epithelial cell membranes have three regions (domains) different in structure and function; apical, lateral and basal.
Surface epithelium consists of one or more cell layers, stacked over a thin basement membrane. Based on the cell shape, epithelial tissue is classified into squamous, cuboidal or columnar. Depending on the number of layers, the tissue is divided into simple or stratified. Subclassifications include pseudostratified, ciliated or transitional.
