Types of Junctions

Adherens Junctions, Desmosomes and Hemidesmosomes (Anchoring Junctions)
Adherens Junctions, Desmosomes and Hemidesmosomes (Anchoring Junctions)

Adherens Junctions; or; Desmosomes; Adherens junctions link actin fibers in adjacent cells together. Desmosomes attach to intermediate filaments of the cytoskeleton. Desmosomes are the strongest cell-cell connections. Desmosomes may be small points of contact between two cells (spot desmosomes) or bands that encircle the entire cell (belt desmosomes). In addition, there are also two types of cell-matrix anchoring junctions: hemidesmosomes and focal adhesion.

Gap Junctions

The gap junction plaque is a relatively large area of membrane observed in TEM thin section and freeze fracture (FF) seen filled with trans-membrane proteins in both tissues and more gently treated gap junction preparations.

Tight Junctions (Occluding Junctions)

Tight junctions, also known as occluding junctions or zonulae occludentes (singular, zonula occludens) are multiprotein junctional complex whose general function is to prevent leakage of transported solutes and water and seals the paracellular pathway.
