Tight junctions between muscle cells help muscle tissue function as a unit.

Question

Quizplus · Accepted Answer

Tight junctions are characteristic of epithelial cells, where they help to create a barrier to prevent the passage of materials between cells. In muscle tissue, it is the gap junctions, not tight junctions, that allow muscle cells to function as a unit by facilitating the direct transfer of ions and small molecules between cells, enabling coordinated muscle contraction.
