Question
**Text Transcription:** 6. Identify the following structures on an image of a synapse: - Postsynaptic neuron - Presynaptic neuron - Neurotransmitter - Synaptic cleft - Synaptic vesicles - Receptor for neurotransmitter - Cell adhesion molecules - Axon terminal 7. Describe the actions of sodium and potassium during action potential generation as it relates to depolarization, repolarization, and hyperpolarization. State the directional flow of each ion and the state of the gated channels for each stage. See figure 12.15 in the textbook. **Explanation of the Diagram:** The diagram illustrates a synapse, highlighting key structures involved in neuronal communication: - **Presynaptic Neuron:** This is the neuron that sends the signal. It is depicted on the left side of the synapse, with its axon terminal releasing neurotransmitters. - **Postsynaptic Neuron:** This is the neuron that receives the signal. It is depicted at the bottom of the synapse, with receptors on its surface. - **Axon Terminal:** The terminal end of the presynaptic neuron, shown enlarged on the right, where synaptic vesicles are located. - **Synaptic Vesicles:** Small spherical entities within the axon terminal are shown releasing neurotransmitters into the synaptic cleft. - **Neurotransmitter:** Molecules shown as blue dots being released by synaptic vesicles into the synaptic cleft. - **Synaptic Cleft:** The space between the presynaptic and postsynaptic neurons where neurotransmitters are released. - **Receptor for Neurotransmitter:** Structures on the postsynaptic neuron that bind neurotransmitters, initiating an electrical signal. - **Cell Adhesion Molecules:** These structures help maintain synaptic structure and stability, depicted between the presynaptic and postsynaptic neurons. This visual aids in understanding the complex process of synaptic transmission and the role each component plays in neuronal communication.

Expert Solution
Step 1: Introduce about the synapse

Transmission of nerve impulse from one neuron to the next neuron occurs at the synapses. There are two types of synapses that are present: electrical synapses and chemical synapse. In case of chemical synapse neurotransmitters are released from the presynaptic neuron.
