Tight junctional complexes are communication openings between odontoblasts that transmit electrical impulses and small molecules.

Question

Quizplus · Accepted Answer

Tight junctional complexes are not communication openings for transmitting electrical impulses and small molecules between odontoblasts; they primarily function to seal neighboring cells together in an epithelial sheet to prevent the passage of molecules and ions through the space between cells. Communication of electrical impulses and small molecules is typically facilitated by gap junctions, not tight junctions.
