Three types of nerve fibres and their terminals have been revealed in the sturgeon neurohypophysis. Peptidergic A1 and A2 type fibres contain granules 120--200 and 100--160 nm in diameter, resp. Monoaminergic B type fibres have granules 80-100 nm in diameter. Terminals of A2 type predominate in the sturgeon neurohypophysis, A1 and B type terminals are a rarer occurrence. Different stages of exocytosis of the neurosecretory granule content were seen in the A1 and A2 type terminals. It is suggested that neurosecretory granules are the carriers of arginine-8-vasotocin and oxytocin-like polypeptide in A2 and A1 fibres, resp.
在鲟鱼神经垂体中已发现三种类型的神经纤维及其终末。肽能A1和A2型纤维分别含有直径为120 - 200纳米和100 - 160纳米的颗粒。单胺能B型纤维含有直径为80 - 100纳米的颗粒。A2型终末在鲟鱼神经垂体中占主导地位，A1和B型终末较少见。在A1和A2型终末可见神经分泌颗粒内容物胞吐的不同阶段。提示神经分泌颗粒分别是A2和A1纤维中精氨酸 - 8 - 血管加压素和催产素样多肽的载体。
