Physiotherapy question and answers, MCQ for physiotherapy entrance

The correct answer is **A. Gap junctions**

Here's why:

* **Gap junctions:** These are specialized intercellular connections that directly connect the cytoplasm of two cells, allowing for the passage of ions, small molecules, and electrical signals. This is crucial for coordinated cellular activity and communication in epithelial tissues.

Let's look at why the other options are incorrect:

* **Tight junctions:** These junctions form a tight seal between epithelial cells, preventing paracellular (between cells) transport of molecules and ions. They maintain cell polarity and prevent leakage.
* **Desmosomes:** These junctions provide strong adhesion between cells, resisting mechanical stress. They're anchored to intermediate filaments within the cell.
* **Hemidesmosomes:** These junctions anchor epithelial cells to the underlying basement membrane.
