MICROANATOMY

Detailed explanation-1: -Desmosomes link one cell to another cell through intermediate filaments. They are also found in many different types of cells. Hemidesmosomes link cells to the matrix through intermediate filaments. Certain hemidesmosome components also bind to F-actin (e.g. plectin [3]).

Detailed explanation-2: -Adhering Junctions Epithelial cells are held together by strong anchoring (zonula adherens) junctions. The adherens junction lies below the tight junction (occluding junction). In the gap (about 15-20nm) between the two cells, there is a protein called cadherin-a cell membrane glycoprotein.

Detailed explanation-3: -A desmosome involves a complex of proteins. Some of these proteins extend across the membrane, while others anchor the junction within the cell. Cadherins, specialized adhesion proteins, are found on the membranes of both cells and interact in the space between them, holding the membranes together.
