NEET BIOLOGY

Detailed explanation-1: -Adherens junctions and desmosomes hold cells together and are formed by transmembrane adhesion proteins that belong to the cadherin family.

Detailed explanation-2: -Anchoring junctions are protein complexes that mediate the adhesion of cells to other cells or to the extracellular matrix.These multiprotein complexes are found in all cell types where they they stabilize the cells position, provide stability and rigidity, and support tissue integrity by holding cell sheets together.

Detailed explanation-3: -Desmosomes (also called anchoring junctions) function like rivets, fastening cells Together into strong sheets. Intermediate Filaments made of sturdy keratin proteins Anchor desmosomes in the cytoplasm. Gap junctions (also called communicating junctions) provide cytoplasmic channels from one cell to an adjacent cell.

Detailed explanation-4: -Adhering Junctions Epithelial cells are held together by strong anchoring (zonula adherens) junctions. The adherens junction lies below the tight junction (occluding junction).
