Quizplus · Accepted Answer

Tight junctions are the most suitable type of intercellular junction for the blood-brain barrier as they create a nearly impermeable seal between cells, preventing any substances from passing through. Desmosomes, gap junctions, and ion channels allow some degree of communication and exchange between neighboring cells.
