Question

Ions and small molecules are able to travel from cell to cell in the heart allowing the cells to beat together. What type of specialized cell junctions would allow this to occur?
Group of answer choices

Tight Junctions

Desmosomes

Gap Junctions

All of the above

Answer 1

The specialized cell junctions that allow ions and small molecules to travel from cell to cell in the heart, enabling the cells to beat together, are **Gap Junctions**. Gap junctions are intercellular connections that facilitate the direct transfer of electrical signals and small molecules between adjacent cells, which is crucial for coordinated cardiac muscle contractions.

So the correct answer is **Gap Junctions**.
