Question

what is a cell junction describe different types of cell Junction​

Answer 1

Answer:

In vertebrates, there are three major types of cell junction: Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions) Gap junctions (communicating junction) Tight junctions (occluding junctions

Answer 2

Answer:

Explanation: Cell Junction:- The epithelial cells are connected to each other laterally as well as to the basement membrane by junctional complexes called cell junction.

There are 5 types of cell junctions :-

1. Tight junction (TJs) :- These junctions maintain cell polarity, prevent lateral diffusion of proteins and ions.
2. Gap junction (GJ) :- This intercellular connection allows passage of ions and small molecules between cells as well as exchange of chemical messages between cells.
3. Hemidesmosomes :- Allows the cells to strongly adhere to the underlying basement membrane. These maintain tissue homeostasis by signaling.
4. Adherens junction :- It is involved in various signaling pathways and transcriptional regulations.
5. Desmosomes :- These provides mechanical strength to epithelial tissue, cardiac muscles and meninges.
