उत्तर
The different types of cell junctions are as follows:
- Gap Junctions (GJs):
These are intercellular connections that allow the passage of ions and small molecules between cells as well as the exchange of chemical messages between cells. - Adherens Junctions (AJs):
They are involved in various signalling pathways and transcriptional regulations. - Desmosomes (Ds):
They provide mechanical strength to epithelial tissue, cardiac muscles and meninges. - Hemidesmosomes (HDs):
They allow the cells to strongly adhere to the underlying basement membrane. These junctions help maintain tissue homeostasis by signalling. - Tight junctions (TJs):
These junctions maintain cell polarity, prevent lateral diffusion of proteins and ions.
