摘要: A chemical transmitter is specifically released from the presynaptic element during stimulation. The must therefore be supplied to terminal in order maintain release at a sufficient rate. This can achieved either by synthesizing substance compartment, an efficient and rapid uptake of into terminal, or both. When synthesis depends on specific enzyme, then localization enzyme probably better marker for that nerve than itself, which may redistributed diffusion neighboring structures (Fonnum, 1912a).
