Question

Order the following events that occur in the synapse from 1-7

1. Ion channels close

2. Neurotransmitters are taken back up out of the synapse or degraded by enzymes in the cleft

3. Ion channels open to stimulate the action potential in the next neuron

4. Signal arrives at the synaptic terminals

5. Influx of Calcium ions

6. Synaptic vesicles fuse to the membrane and release neurotransmitters into the synapse

7. Neurotransmitters bind to ion channels on the dendrites on the other side of the synapse

Answer 1

A synapse is the junction between 2 neurons.In chemical synapses,the signals are transffered via the neurotransmitters in the synapse.

the correct order of events in a synapse are

• Signal arrives at the synaptic terminals
• Influx of Calcium ions
• Synaptic vesicles fuse to the membrane and release neurotransmitters into the synapse
• Neurotransmitters bind to ion channels on the dendrites on the other side of the synapse
• Ion channels open to stimulate the action potential in the next neuron
• Neurotransmitters are taken back up out of the synapse or degraded by enzymes in the cleft
• Ion channels close
