What is cell junction describe different types of cell junctions?
In vertebrates, there are three major types of cell junction: Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions) Gap junctions (communicating junction) Tight junctions (occluding junctions)Click to see full answer.

In vertebrates, there are three major types of cell junction: Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions) Gap junctions (communicating junction) Tight junctions (occluding junctions)Click to see full answer. Similarly, you may ask, what are the three types of cell junctions and what are their functions? As shown in Figure 1, three kinds of cell junctions are recognized: Desmosomes are protein attachments between adjacent cells. Tight junctions are tightly stitched seams between cells. Gap junctions are narrow tunnels between cells that consist of proteins called connexons. what type of cells have tight junctions? Tight junctions seal adjacent epithelial cells in a narrow band just beneath their apical surface. They consist of a network of claudins and other proteins. Tight junctions perform two vital functions: They limit the passage of molecules and ions through the space between cells. Subsequently, one may also ask, what are the different types of intercellular junctions? Three different types of intercellular junctions can be distinguished according to their function: Tight or occluding junctions. Adherent or anchoring junctions, including desmosomes and hemidesmosomes. Gap junctions. Where are cell junctions located?Location. Gap junctions are found in many places throughout the body. This includes epithelia, which are the coverings of body surfaces, as well as nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Their primary role is to coordinate the activity of adjacent cells.
