Question

Match column-I showing neuroglial cells with their functions in column-II:

	Column I		Column II
i.	Astrocytes	a.	production of CSF.
ii.	Oligodendrocytes	b.	maintenance of blood brain barrier
iii.	Ependymal cells	c.	formation of white matter of CNS.
iv.	Schwann cells	d.	production of myelin sheath around medullated nerves of PNS.

पर्याय

• i - a, ii - d, iii - b, iv - c

• і - c, ii - b, iii - a, iv - d

• i - b, ii - c, іii - а, iv - d

• i - d, ii - a, iii - c, iv - b

Answer 1

	Column I		Column II
i.	Astrocytes	b.	maintenance of blood brain barrier
ii.	Oligodendrocytes	c.	formation of white matter of CNS.
iii.	Ependymal cells	a.	production of CSF.
iv.	Schwann cells	d.	production of myelin sheath around medullated nerves of PNS.

Explanation:

Astrocytes maintain the blood-brain barrier, while ependymal cells are responsible for producing cerebrospinal fluid (CSF). Oligodendrocytes form the myelin sheath in the central nervous system (white matter), whereas Schwann cells perform this same function for the peripheral nervous system.
