Question:
Glial cells which regulate maintenance of Blood Brain Barrier are __________.
Glial cells which regulate maintenance of Blood Brain Barrier are __________.
Show Hint
Think of the star-shaped glial cells whose end feet touch brain capillaries.
Updated On: Nov 12, 2026
- ependymal cells
- microglia
- astrocytes
- oligodendrocytes
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Neuroglia are supporting cells of the nervous system, and each type has its own job.
Step 2: Match the job
Astrocytes are star-shaped and their end feet wrap the brain capillaries, helping to form and maintain the blood-brain barrier.
Step 3: Why the others fail
Ependymal cells line the ventricles, microglia are phagocytic defence cells, and oligodendrocytes form myelin in the CNS.
Final Answer:
Astrocytes maintain the blood-brain barrier. \[ \boxed{\text{(C) }\text{astrocytes}} \]
