Multiple Choice

What are the primary functions of anchoring junctions in cells?

To prevent the passage of substances between cells by forming a barrier

To facilitate the exchange of ions and small molecules between adjacent cells

To allow cells to communicate through chemical signals

To provide mechanical stability by connecting the cytoskeletons of adjacent cells

Verified step by step guidance

Understand that anchoring junctions are specialized structures in cells that connect the cytoskeletons of adjacent cells.

Recognize that the primary function of anchoring junctions is to provide mechanical stability to tissues by holding cells together.

Identify the types of anchoring junctions, such as desmosomes and adherens junctions, which are involved in maintaining tissue integrity.

Note that anchoring junctions are different from tight junctions, which prevent the passage of substances between cells, and gap junctions, which facilitate communication between cells.

Conclude that anchoring junctions are crucial for tissues that experience mechanical stress, such as skin and heart muscle, by ensuring cells remain connected and stable.
