The correct Answer is:
To answer the question "A synapse is formed by," we can break down the components that make up a synapse step by step. ### Step-by-Step Solution: 1. **Understanding Synapse**: - A synapse is a junction between two neurons where communication occurs. It is essential for transmitting signals in the nervous system. 2. **Identifying Components**: - A synapse consists of three main components: - **Pre-synaptic membrane**: This is the membrane of the neuron that sends the signal. It contains vesicles filled with neurotransmitters. - **Post-synaptic membrane**: This is the membrane of the neuron that receives the signal. It has receptors that bind to the neurotransmitters released from the pre-synaptic neuron. - **Synaptic cleft**: This is the small gap between the pre-synaptic and post-synaptic membranes where neurotransmitters are released and diffuse across to transmit the signal. 3. **Conclusion**: - Therefore, a synapse is formed by the combination of the pre-synaptic membrane, post-synaptic membrane, and the synaptic cleft. 4. **Final Answer**: - The correct answer to the question is "all of these," as all three components are essential for the formation of a synapse.
