1. | Impulse Transmission across a chemical synapse is always faster than that across an electrical synapse. |
2. | The membranes of presynaptic and postsynaptic neurons are in close proximity in an electrical synapse. |
3. | Electrical current can flow directly from one neuron into the other across the electrical synapse. |
4. | Chemical synapses use neurotransmitters. |
