neurosecretory substancemedical dictionary

The secretion of nerve cell bodies located in the hypothalamus; the substance is transported by way of hypothalamo-hypophysial tract fibres into the neurohypophysis where the terminals of the nerve fibres contain the secretion. As seen in the fibres and terminals with a light microscope, the substance appears as Herring bodies or hyaline bodies of the pituitary (see under body).

See: hyaline bodies of pituitary.
