Intercellular connections refer to the various ways that cells communicate and adhere to one another within tissues. These connections are crucial for maintaining the structure and function of tissues in organisms. They include structures like tight junctions, gap junctions, and desmosomes, each serving specific roles in cell adhesion and signaling. Tight junctions create a barrier that prevents substances from passing between cells, while gap junctions allow for direct communication by enabling the transfer of ions and small molecules. Desmosomes provide mechanical strength by anchoring cells together, ensuring that tissues can withstand stress and maintain their integrity.
