Abstract
The relationship of the neurosecretory system to the anterior pituitary gland was investigated bei rabbits by a modification of HALMI's staining. The results were as follows:
Some neurosecretory granules of the hypothalamo-hpyophysial neurosecretory fibers enter into the intercellular spaces of the pars tuberalis and of the frontal half part of the pars distalis via the primary blood capillaries of the hypophysial portal system and their perivascular spaces.
Some neurosecretory granules enter into the intercellular spaces in the caudal half part of the pars distalis via the pars intermedia from the pars nervosa.
The hypothesis that the hypothalamic neurosecretory material controls the function of the anterior pituitary gland, is therefore from the morphological view point much more supported.
