tight junction
This term is a technical biological descriptor used primarily in histology and cell biology. It describes a specific type of intercellular seal that regulates the permeability of epithelial and endothelial layers, ensuring that substances must pass through the cells rather than between them.
In a clinical or research context, the term is often discussed in relation to the blood-brain barrier or the intestinal lining. It is a precise anatomical term and does not have a metaphorical or casual equivalent in standard English usage.
