What is cell junction? Describe different type of cell junction.
Answers
Answer:
Cell Junctions :
The cells are held together by specialised intercellular junctions, which serve as structural and functional links between them.
Three types of cell junctions are found in the epithelium and other tissues as well.
These are :
- Tight Junctions (Zonula Occludens)
- Gap Junctions
- Adhering Junctions (Macula adherens)

Answer:
Cell Junctions are the junctions that provide structural and functional links between adjacent cells
There are three types of cell junctions.
The different types of cell junctions include tight junctions, adhering junctions and gap junctions.
The tight junctions help in stopping substances from leaking across a tissue.
The adhering junctions perform cementation of the cells to keep neighbouring cells together
The gap junctions facilitate the cells to communicate with each other by connecting cytoplasm of adjoining cells. This also helps in rapid transfer of ions, small molecules and big molecules.
