CELL JUNCTION

A 'cell junction' is a structure within a tissue of a multicellular organism. Cell junctions are especially abundant in epithelial tissues. They consist of protein complexes and provide contact between neighbouring cells, between a cell and the extracellular matrix, or they built up the paracellular barrier of epithelia and control the paracellular transport.
In vertebrates, there are three major types of cell junctions:

★ Adherens junctions and Desmosomes

★ Gap junctions

★ Tight junctions
Invertebrates have several other types of specific junctions, for example Septate junctions or the CeAJ (C. elegans apical junction).
