Synaptic Transmission
Flowchart: Synaptic transmission
Flowchart content
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
