<span>Narrow junctions and desmosomes have different structures. Narrow junctions are made of a protein arranged inside the membrane. There are many intersecting lines that cause the cells to be sealed and together. Desmosomes contain the protein cadherin.

The desmosomes provide binding sites for the cells to be attached.</span>
