Questions and Answers

What is primarily the function of desmosomes?

Attach cells to non-cellular surfaces.

Facilitate communication between adjacent cells.

Connect one cell to another in superficial layers. (correct)

Anchor epithelial cells to connective tissue.

Which statement accurately describes hemidesmosomes?

They contain a larger attachment plaque than desmosomes.

They connect a cell to an adjacent non-cellular surface. (correct)

They are formed entirely between two adjacent cells.

They are released during tissue turnover.

During tissue repair, what happens to desmosomes?

They dissociate and do not reform.

They are formed as cells migrate to new locations. (correct)

They reinforce connections between tissues.

They weaken, resulting in cell detachment.

Study Notes

Intercellular Junctions

Intercellular junctions are formed between cells and between cells and non-cellular surfaces
These junctions act as mechanical attachments

Desmosomes

Desmosomes are junctions formed between cells
They are primarily found in the superficial layers of skin and oral mucosa
Desmosomes are released during tissue turnover
Cells are reattached in new locations during tissue migration such as during tissue repair

Hemidesmosomes

Hemidesmosomes connect cells to non-cellular surfaces
They are crucial for connecting epithelium to connective tissue, such as the basement membrane, in skin and oral mucosa
Structurally, a hemidesmosome is half a desmosome with a smaller attachment plaque containing only tonofilaments on its cellular side

Clinical Relevance

Hemidesmosomes contribute to gingival tissue attachment to tooth surfaces, like the attachment between nails and nail beds

Description

This quiz explores intercellular junctions, focusing on desmosomes and hemidesmosomes, including their structure and clinical relevance. Learn about how these junctions contribute to tissue integrity and repair, particularly in skin and oral mucosa. Test your knowledge on their roles in connecting cells and tissue surfaces.
