Question

Quizplus · Accepted Answer

Keratinocytes are connected through desmosomes, which are specialized junctions that provide strong adhesion between cells. Desmosomes are made up of proteins called desmoglein and desmocollin, which link to the intermediate filaments of the cytoskeleton within the cell. This allows for the formation of a strong, mechanical bond between neighboring cells, which is important for maintaining the integrity of the skin. Keratin, prekeratin, collagen fibers, and elastic fibers are all components of the extracellular matrix of the skin, but they do not directly connect keratinocytes to each other.
