Discover how the blood-brain barrier forms and its vital role in protecting the brain from harmful substances.

525 views

The blood-brain barrier is formed by endothelial cells lining the brain's capillaries. These cells are tightly joined, creating a selective barrier that protects the brain from harmful substances while allowing essential nutrients to pass through. Astrocytes, a type of glial cell, support the endothelial cells, maintaining the barrier's integrity. This specialized system is crucial for maintaining the brain's stable environment and facilitating proper neurological function.

FAQs & Answers

  1. What are the main functions of the blood-brain barrier? The blood-brain barrier protects the brain from harmful substances while allowing essential nutrients to pass through.
  2. How do astrocytes support the blood-brain barrier? Astrocytes help maintain the integrity of the blood-brain barrier by supporting the endothelial cells.
  3. Why is the blood-brain barrier important for neurological function? It ensures a stable environment for the brain, crucial for maintaining proper neurological functions.
  4. What can damage the blood-brain barrier? Various factors such as inflammation, high blood pressure, and certain diseases can damage the blood-brain barrier, compromising brain health.
