Webb1 nov. 2024 · During neuromuscular transmission, packets of 5000–10,000 molecules of ACh released from each synaptic vesicle synchronously activate thousands of individual postsynaptic AChRs. The single-channel currents they produce consequently summate, causing miniature and evoked transmembrane endplate currents (MEPCs and EPCs).
