Question

The glial cells which help in providing blood-brain barrier are

• A. Astrocytes
• B. Ependymal cells
• C. Microglial cells
• D. Oligodendrocytes

Answer 1

Answer: (A)

Astrocytes

• Glial cells are also called neuroglia which are non-neuronal cells that surround the neurons and provide support and insulation. These cells maintain homeostasis.
• The glial cells are of a number of types, which include oligodendrocytes, astrocytes, ependymal cells, schwann cells, microglia, and satellite cells.
• However, astrocytes have numerous projections that link neurons to their blood supply and forms the blood-brain barrier. They are also responsible for the repair of damaged areas of nervous tissue.

So, the correct answer is option A.
