The releasing pattern of secretory granules or polypeptide hormones of neurohypophysis involves a whole-releasing pattern together with granular membrane. After released into perivascular space, they enter easily into cerebrospinal fluid via interspace of tissue and epithelial openings rather than into blood circulation through the walls of capillaries, and then into the cerebrospinal fluid.

神经垂体多肽激素分泌颗粒的释放形式，存在一种连同颗粒被膜的整体释放；释放入血管周隙内的多肽激素或分泌颗粒，更易经组织间隙、囊上皮孔进入脑脊液，而非直接透过毛细血管壁进入血液循环再进入脑脊液中。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
