<prompt> Epithelial cells get clues about the nature of their neighbors from:Macula adherensZonula adherensConnexonsZonula occludens  <response>: Zonula adherens or adhering junctions provide such clues to epithelial cells, leading eventually to formation of a coherent epithelium. Zonula adherens and desmosome helps to hold cells together, and the hemidesmosome and focal adhesions attach cells to their basal laminas. The gap junction makes - cytoplasmic tunnel for diffusion of small molecules 1000 Da between two neighboring cells.
