Final answer:
At the transition from E-cadherin to N-cadherin, a desmosome structure is formed. Desmosomes act like spot welds, connecting cells and providing strength to tissues. They are created by the linkage of cadherins and intermediate filaments.
Step-by-step explanation:
At the transition from E-cadherin to N-cadherin, a structure called a desmosome is formed. A desmosome acts like a spot weld between cells, providing a strong adhesive connection. It is created by the linkage of cadherins and intermediate filaments. Cadherins are short proteins in the cell membrane that connect to intermediate filaments, which are part of the cytoskeleton, strengthening the intercellular attachments and the tissue cell layer.
