A) Desmosomes regulate skin cell development.
B) Desmosomes maintain the continuity of skin tissue.
C) Desmosomes increase the migration of cells within skin tissue.
D) Desmosomes maintain internal structures within skin cells.
E) Desmosomes increase access of skin cells to extracellular fluids.

Quizplus · Accepted Answer

The disorder described disrupts linkages between proteins in desmosomes, which are a type of cell junction that maintain the continuity of skin tissue. Therefore, this disorder indicates that cell junctions, specifically desmosomes, play an important role in maintaining the integrity of skin tissue.
