Question
The image depicts a synaptic junction with labeled structures. These structures are part of the neurotransmission process. Below the diagram, there's an activity to match each lettered label with its correct structure name. **Diagram Explanation**: - **A**: Unlabeled structure not specifically referenced in the activity. - **B**: Circular structures inside the presynaptic neuron. - **C**: Structures located in the synaptic cleft. - **D**: Vertical structures or shapes on the postsynaptic side. - **E**: Vertical structures similar to D. - **F**: Circular structures on the presynaptic neuron. - **Y**: A curved line indicating the boundary of another structure. **Matching Activity**: The task asks to match the letters (B, C, D, E, F, Y) with the following structure names: - Receptor Protein - Pre-synaptic vesicle in axon terminal - Neurotransmitters - Reuptake Inhibitor - Synapse - Dendrite **Buttons for Matching**: Each letter has a corresponding box to match with the names of the structures listed below by filling in the correct term in each box.

**HBS 2.2.2 Activity: Neuronal Communication Sequence** Organize the following steps in the sequence they occur after one neuron sends a message to the next neuron: 1. **Dendrites receive neurotransmitters from synapse.** - The dendrites of the neuron detect and capture neurotransmitters released from the synaptic cleft of the previous neuron. 2. **Neuron depolarization occurs going from -70mV to 30mV.** - The cell membrane's potential changes, becoming less negative as sodium ions flood into the cell, moving from a resting potential of -70mV to a peak potential of 30mV. 3. **Sodium channels open.** - Specific channels in the neuron's membrane open to allow sodium ions to enter, initiating depolarization. 4. **Sodium channels close and potassium channels open.** - After reaching peak depolarization, sodium channels close, and potassium channels open, allowing potassium ions to exit the neuron. 5. **Neuron repolarization occurs going from 30mV to -90mV.** - The efflux of potassium ions causes the neuron to become more negative, surpassing the initial resting potential, reaching approximately -90mV. 6. **Potassium channels close.** - Once repolarization is complete, potassium channels close to prevent further ion movement. 7. **Sodium potassium pump restores neuron to -70mV.** - The sodium-potassium pump actively restores the resting potential by moving sodium ions out and potassium ions into the neuron, reestablishing the original -70mV membrane potential. This sequence of events is crucial for understanding how neuronal messages are transmitted, ensuring proper nervous system function.
