WebSimple squamous epithelial cells are thin and flat (the thinnest of all epithelial cell-types), which allows them to have a large surface area that is exposed to the lumen on one side (the apical surface), and to the basement membrane (i.e. basal lamina) on the other (the basolateral surface; Figure 1). The cells, scale-like in appearance, tend ... WebSince our cell membrane has a very large hydrophobic region, it prefers nonpolar molecules. And since these phospholipids are packed so closely together, our cell membrane also prefer small molecules to pass through. So our cell membrane is semi-permeable, allowing, generally, small and nonpolar molecules to pass through the cell …
