Definitions:

Intercellular Junction

Specialized structures that connect adjacent cells together, facilitating communication and the passage of molecules between cells.

Small Molecules

Organic compounds with low molecular weight, often used in pharmacology for their ability to modulate biological processes.

Desmosome Junctions

Cell structures specialized for cell-to-cell adhesion, particularly in tissues subjected to mechanical stress, binding cells together to form a strong layer or sheet.

Tight Junctions

Specialized connections between adjacent cells in animal tissues that create a barrier to prevent leakage of materials through intercellular spaces.
