| I: | Myelinated nerve fibres are enveloped with Schwann cells, which form a myelin sheath around the axon. | 
| II: | Unmyelinated nerve fibre is not enclosed by a Schwann cell or a myelin sheath. | 
| III: | Myelinated nerve fibres are found in spinal and cranial nerves. | 
| IV: | Unmyelinated nerve fibres are commonly found in autonomous and somatic neural systems. | 
| 1. | Only II is incorrect | 2. | I and II are correct | 
| 3. | III and IV are incorrect | 4. | All are correct | 
| Statement I: | Dendrites transmit impulses towards the cell body of the neuron. | 
| Statement II: | The axons transmit nerve impulses away from the cell body to a synapse or to a neuro-muscular junction. | 
| I: | are neither clearly sensory nor motor in function. | 
| II: | are for complex functions like inter-sensory associations, memory and communication. |
