Question: What role do neurotransmitters play in synaptic transmission?

Options:

1. They generate action potentials
2. They transmit signals across the synaptic cleft
3. They maintain resting membrane potential
4. They recycle ions

Correct Answer: They transmit signals across the synaptic cleft

Solution:

Neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, facilitating signal transmission.
