supraopticohypophysial tract


A bundle of unmyelinated fibres originating from all cells of the supraoptic nucleus and an estimated 20% of those of the paraventricular nucleus of the hypothalamus, which extend through the infundibulum and pituitary stalk to their endings in the posterior lobe of the hypophysis; the fibres convey neurosecretory substances, vasopressin and oxytocin, which are stored in (and can be released into the circulating blood from) their terminals.

See: hypophysis, neurosecretion.

Synonym: tractus supraopticohypophysialis, hypothalamohypophysial tract.
