Final answer:
Electrical signals in neurons are rapidly transmitted through gap junctions, which are direct intercellular connections that allow for quick communication. The correct option is (A).
Step-by-step explanation:
In electrical synapses, electrical signals move quickly from cell to cell through gap junctions.
Unlike chemical synapses, where neurotransmitters are released from synaptic vesicles into the synaptic cleft to bind with neurotransmitter receptors on the dendrite of an adjacent neuron, electrical synapses allow for direct electrical communication between neurons.
The gap junctions consist of connexin proteins that form channels allowing ions and small molecules to pass directly from one cell to another, facilitating rapid signal transmission.
