Answer 1

Answer:

Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions) Gap junctions (communicating junction) Tight junctions (occluding junctions

I hope this answer is correct

Answer 2

Explanation:

In vertebrates, there are three major types of cell junction: Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions) Gap junctions (communicating junction).

Anherens junction:

Adherens junctions are protein complexes that occur at cell–cell junctions in epithelial and endothelial tissues, usually more basal than tight junctions. An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton.

Anchoring junction:

Anchoring junctions are cell junctions that are anchored to one another and attached to components of the extracellular matrix. They are important in keeping the cells together and structural cohesion of tissues. They are commonly found in tissues that are prone to constant mechanical stress, e.g. skin and heart.

Gap junction:

Gap junctions are a specialized intercellular connection between a multitude of animal cell-types. They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells
