Quizplus · Accepted Answer

Astroglial cells create and maintain the blood-brain barrier, which regulates the passage of substances from the bloodstream into the brain. This barrier protects the brain from harmful substances while allowing necessary nutrients to pass through. Astroglial cells also play a role in the regulation of neurotransmitters and contribute to the structural support of neurons.
