Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The function of desmosomes is to
A
secrete substances.
B
allow materials to pass through a cell membrane.
C
carry our genetic information.
D
connect neighboring cells together.
Explanation: 

Detailed explanation-1: -Through desmosomes, the intermediate filaments of adjacent cells are linked into a net that extends throughout the many cells of a tissue.

Detailed explanation-2: -Desmosomes represent major intercellular adhesive junctions at basolateral membranes of epithelial cells and in other tissues. They mediate direct cell-cell contacts and provide anchorage sites for intermediate filaments important for the maintenance of tissue architecture.

Detailed explanation-3: -Desmosomes are adhesive intercellular junctions that mechanically integrate adjacent cells by coupling adhesive interactions mediated by desmosomal cadherins to the intermediate filament cytoskeletal network.

Detailed explanation-4: -Cell junctions The three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes. These types of junctions have different purposes, and are found in different places.

Detailed explanation-5: -Introduction. Desmosomes are intercellular junctions that provide strong adhesion between cells. Because they also link intracellularly to the intermediate filament cytoskeleton they form the adhesive bonds in a network that gives mechanical strength to tissues.
