Resource summary

Flowchart nodes

  • An impulse arrives at the presynaptic knob
  • Post-synaptic membrane depolarised causing action potential
  • Voltage-dependant calcium channels open, causing influx of Ca+ ions
  • Synaptic vesicles contain acetylcholine bind to presynaptic membrane and releases neurotransmitter by exocytosis into synaptic cleft
  • Neurotransmitter diffuses to receptor on a protein on post-synaptic membrane
  • Co-operative binding on receptor: 2 receptor sites
  • Threshold reached (-55mV)
  • Channel opens and Na+ ions diffuse in
  • Acetylcholine hydrolysed or destroyed by enzyme
