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. |
Receptor sites for neurotransmitters are present on:
1. Pre-synaptic membrane
2. Tips of axons
3. Post-synaptic membrane
4. Membrane of synaptic vesicles
A diagram showing the axon terminal and synapse is given. Identify correctly at least two of A-D:
1. B- Synaptic connection; D- K+
2. A- Neurotransmitter; B- Synaptic cleft
3. C- Neurotransmitter; D- Ca++
4. A- Receptor; C- Synaptic vesicles
