Cellular junctions are specialized structures that facilitate cell adhesion and communication. The main types include:
- Tight Junctions: These junctions create a seal between adjacent cells, preventing the passage of molecules between them. - Desmosomes: These are anchoring junctions that provide mechanical strength to tissues by linking the cytoskeletons of adjacent cells. - Gap Junctions: These allow for the direct passage of ions and small molecules between neighboring cells, facilitating rapid communication.
