The cell junctions allowing exchange of cytoplasmic molecules between the two cells are called: (DNB Pattern)
Two types of junctins form between the cells that make up tissues.
- Junctions that fastens the cells to one another and to surrounding tissues.
- Junctions that permit transfer of ions and other molecules from one cell to another.
The junction that tie cells together and endow tissues with strength and stability include the tight junction, which is also called zonula occludensQ The desmosomes and zonula adherens holds cells together and the hemidesmosome and focal adhesion attatch cells to their basal laminas. Tight junctins between epithelial cells are also essential for transport of ions across epithelia. The junction by which molecules are transferred is the gap junction Q.
