The correct answer is saltatory conduction of nerve impulse. Nodes of Ranvier are small gaps in the myelin sheath of axons that allow for the rapid transmission of electrical signals by enabling the action potentials to jump from one node to another. This process, known as saltatory conduction, significantly increases the speed of nerve signal transmission compared to continuous conduction along unmyelinated fibers.

In contrast, the other options are incorrect. 'More diffusion of neurotransmitters' does not relate to the function of Nodes of Ranvier; neurotransmitter diffusion occurs at synapses, not along the axon. 'Formation of new synaptic connections' and 'Synthesis of new neurons' are also unrelated to the role of Nodes of Ranvier, as these processes pertain to different aspects of neural function and development.

This option is incorrect as Nodes of Ranvier do not relate to the diffusion of neurotransmitters. Instead, they are involved in the conduction of electrical impulses along the axon.

This option is correct because Nodes of Ranvier facilitate saltatory conduction, where electrical impulses jump from one node to the next, speeding up the transmission of signals along the axon.

This option is incorrect as the Nodes of Ranvier do not contribute to the formation of synapses. Their primary function is to assist in the rapid transmission of action potentials along the axon.

This option is incorrect because Nodes of Ranvier are not involved in the synthesis of new neurons. They play a role in the conduction of nerve impulses, not in neurogenesis.
