What does the arrival of an impulse cause?
Permeability of the presynaptic knob to alter and Calcium ions can enter in
1 of 5
What does the influx of calcium ions cause?
vesicles containing neurotransmitters to fuse with the membrane and release neurotransmitters into the synaptic cleft
2 of 5
What do the neurotransmitters do?
They diffuse across the synaptic clefts and bind to the receptors on the sodium ion channels on the post synaptic membrane
3 of 5
What happens once the neurotransmitters have binded to the receptors?
Sodium ion channels open and allow the diffusion of sodium ions across the synaptic cleft
4 of 5
What is at least one function of a synapse?
To ensure unidirectional flow
