Question

Most abundant glial cells of CNS are?

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

Hint:

Astrocytes play key roles in the support and maintenance of neurons and are crucial for proper CNS function.

Answer 1

The Correct Option is C

Step 1: Astrocytes are the most abundant type of glial cells in the central nervous system (CNS). They perform a variety of functions, including supporting neurons, maintaining the blood-brain barrier, and regulating blood flow.

Step 2:
- (A) Oligodendrocytes are responsible for the formation of myelin in the CNS but are less abundant than astrocytes.
- (B) Microglia are the resident immune cells of the CNS, responsible for monitoring and clearing debris, but they are fewer in number.
- (D) Ependymal cells line the ventricles and produce cerebrospinal fluid but are not as abundant as astrocytes.

Conclusion: Astrocytes are the most abundant glial cells in the CNS, making \( (C) \) the correct answer.
