Quizplus · Accepted Answer

Ionotropic receptors are responsible for the rapid transmission of electrical signals across synapses. They are ligand-gated ion channels that open or close in response to the binding of a specific neurotransmitter. In this case, the neurotransmitter would be released by the sensory neurons that detect the truck, and the ionotropic receptors would open, allowing sodium ions to flow into the postsynaptic neuron, which would then generate an action potential.
