| List - I | List – II | ||
| A. | Schwann cells | i. | Neurotransmitter |
| B. | Synaptic knob | ii. | Cerebral cortex |
| C. | Bipolar neurons | iii. | Myelin sheath |
| D. | Multipolar neurons | iv. | Retina |
The accurate pairings are:
• Schwann cells produce the myelin sheath surrounding axons. (A-III)
• The synaptic knob houses neurotransmitters. (B-I)
• Bipolar neurons are located in the retina. (C-IV)
• Multipolar neurons are situated in the cerebral cortex. (D-II)
Consequently, the correct selection is (1): A-III, B-I, C-IV, D-II.
