Give four characteristics of the epithelial cells

Cohesion (adhesion molecules and specialized junction system attaches epithelial cells and maintain cohesion between these cells and the basal lamina.)/ morphology (because of the juxtaposition of epithelial cells and basal lamina, they either adopt squamous, cuboidal or cylindrical (columnar) shape) /Presence of intermediate filaments of cytokeratin in their cytoplasm help in polarity/ polarity(Apical pole, Lateral pole and Basal pole) assymmetrical distribution of components of the cytoplasm and of plasma membrane
