The correct Answer is:
To solve the question, "All the following structures are found in an electrical synapse except," we need to analyze the options provided and understand the characteristics of electrical synapses. ### Step-by-Step Solution: 1. **Understand the Types of Synapses**: - There are two main types of synapses: electrical and chemical. - **Electrical Synapses**: These allow direct transmission of electrical signals between neurons through gap junctions. - **Chemical Synapses**: These involve the release of neurotransmitters from synaptic vesicles to transmit signals. 2. **Analyze the Options**: - **Gap Junction**: These are specialized intercellular connections that allow direct communication between adjacent neurons. They are indeed found in electrical synapses. - **Synaptic Vesicles**: These are small membrane-bound structures that store neurotransmitters in chemical synapses. They are not present in electrical synapses. - **Presynaptic Membrane**: This is the membrane of the neuron that releases neurotransmitters or electrical signals. It is present in electrical synapses. - **Postsynaptic Membrane**: This is the membrane of the neuron that receives the signal. It is also present in electrical synapses. 3. **Identify the Incorrect Structure**: - Since synaptic vesicles are associated with chemical synapses and not electrical synapses, they are the only structure listed that is not found in an electrical synapse. 4. **Conclusion**: - The correct answer is **synaptic vesicles** (Option B). ### Final Answer: **Option B: Synaptic Vesicles**
