Question

Match the items given in column I with those given in column II.
Choose the correct option.

	Column I		Column II
a.	Oligodendrocytes	(i)	Synthesize myelin sheath in PNS
b.	Multipolar neurons	(ii)	Cerebral cortex
c.	Schwann cells	(iii)	Synthesize myelin sheath in CNS
d.	Bipolar neurons	(iv)	Retina of eye

• A. a-(iii) , b-(ii), c-(i), d-(iv)
• B. a-(i) , b-(ii), c-(iii), d-(iv)
• C. a-(i) , b-(iv), c-(iii), d-(ii)
• D. a-(iv) , b-(iii), c-(i), d-(ii)

Answer 1

The correct option is A a-(iii) , b-(ii), c-(i), d-(iv)

• Oligodendrocytes help in the formation of the myelin sheath in the CNS and schwann cells help in the formation of the myelin sheath in the PNS.
• The bipolar neurons are relatively rare and are found in the retina of the eye along with the olfactory epithelium and the vestibulocochlear nerve of the ear.
• The multipolar neurons are present in the brain and the spinal cord and hence can be found in the cerebral cortex.

So the correct answer is 'a-(iii) , b-(ii), c-(i), d-(iv)'.
