They represent the terminal end of the axons from the hypothalamus, and hormones are temporarily stored in these locations.
[2] In addition, each Herring body also contains ATP and a type of neurophysin.
Neurophysin and its hormone become a complex considered a single protein and stored in the neurohypophysis.
Upon stimulation by the hypothalamus, secretory granules release stored hormones into the bloodstream.
