Desmosomes
B
Tight junctions
C
Gap junctions
D
Adherens junctions
Verified step by step guidance1
Understand the function of each type of cell junction: Desmosomes, Tight junctions, Gap junctions, and Adherens junctions.
Desmosomes provide strong adhesion between cells, particularly in tissues that experience mechanical stress, but do not facilitate molecule movement.
Tight junctions create a seal between cells, preventing the passage of molecules and ions through the space between cells.
Gap junctions are specialized intercellular connections that allow direct communication between cells by permitting the movement of ions, nutrients, and other small molecules.
Adherens junctions connect the actin cytoskeleton of one cell to another, providing structural support but not facilitating molecule movement.
