Question

___________________ join the intermediate filaments in one cell to those in the neighboring cell. __________________ anchor intermediate filaments in a cell to the extracellular matrix. ___________________ involve cadherin connections between neighboring cells and are anchoring sites for actin filaments. _________________ permit the passage of small molecules from one cell to its adjacent cell. ___________________ prevent the leakage of molecules between adjacent cells.

Answer 1

Desmosomes connect intermediate filaments between cells, hemidesmosomes link them to the extracellular matrix, adherens junctions tether actin filaments at cadherin sites, gap junctions facilitate small molecule passage, and tight junctions block molecule leakage between cells.

Step-by-step explanation:

Desmosomes join the intermediate filaments in one cell to those in the neighboring cell. Hemidesmosomes anchor intermediate filaments in a cell to the extracellular matrix. Adherens junctions involve cadherin connections between neighboring cells and are anchoring sites for actin filaments. Gap junctions permit the passage of small molecules from one cell to its adjacent cell. Tight junctions prevent the leakage of molecules between adjacent cells.
