Which of the following is a property of chemical synapses?
Which of the following is a property of chemical synapses?
- They involve the release of electrical signals
- They release neurotransmitters from the postsynaptic neuron
- They allow for simple synaptic integration
- They have a large gap called the synaptic cleft (correct)
What happens during neurotransmitter release in chemical synapses?
What happens during neurotransmitter release in chemical synapses?
- The presynaptic neuron synthesizes neurotransmitters in the synaptic cleft
- The postsynaptic neuron releases neurotransmitters into the synaptic cleft
- An action potential triggers the release of neurotransmitters from vesicles into the synaptic cleft (correct)
- Neurotransmitters are broken down by enzymes in the synaptic cleft
What is the role of synaptic integration in chemical synapses?
What is the role of synaptic integration in chemical synapses?
- To increase the size of the synaptic cleft
- To allow the postsynaptic neuron to receive input from multiple presynaptic neurons (correct)
- To decrease the amount of neurotransmitters released by the presynaptic neuron
- To prevent the postsynaptic neuron from generating an action potential
