Which of the following statement(s) regarding cell junctions is/are correct ?

(a) Tight junctions stop the leakage of substances across the tissue.

(b) Adhering junction help in cementing neighbouring cells together.

(c) Gap junctions facilitate rapid transfer of ions, small molecules between adjoining cells.

A cell junction (or intercellular bridge) is a type of structure that exists within the tissue of some multicellular organisms, such as animals. Cell junctions consist of multiprotein complexes that provide contact between neighbouring cells or between a cell and the extracellular matrix. There are three major types of cell junctions: adherens junctions, desmosomes and hemidesmosomes (anchoring junctions); gap junctions (communicating junction); tight junctions (occluding junctions).
