I mean, we don't know the detailed answer, but we know the basic part of the answer, and that is, there is a sequence of neuron firings, and they terminate where the acetylcholine is secreted at the axon end-plates of the motor neurons.
En realidade non sabemos a resposta en detalle, mais sabemos a parte básica: hai unha secuencia de actividades neuronais que remata onde se segrega a acetilcolina nas terminacións axonais das neuronas motoras.
