Epithelial tissue is made up of carefully packed cells, sure to one another by cell adhesion molecules, with tiny intercellular Area. Epithelial cells might be squamous (flat), cuboidal or columnar and rest with a basal lamina, the higher layer of your basement membrane,[seventeen] the lessen layer would be the reticular lamina lying close to the connective tissue from the extracellular matrix secreted with the epithelial cells.[eighteen] There are many different types of epithelium, modified to suit a particular functionality.
