=== Magnocellular neurosecretory neurons ===
[[File:Gray1181.png|thumb|Magnocellular neurons of the PVN and SON project to the [[posterior pituitary]]]]

The [[magnocellular neurosecretory cell|magnocellular]] cells in the PVN elaborate and secrete two [[peptide hormones]]: [[oxytocin]] and [[vasopressin]].

These hormones are packaged into large vesicles, which are then transported down the [[Myelin|unmyelinated]] axons of the cells and released from neurosecretory nerve terminals residing in the posterior pituitary gland.{{cn|date=May 2022}}

Similar magnocellular neurons are found in the [[supraoptic nucleus]] which also secrete vasopressin and a smaller amount of oxytocin.{{cn|date=May 2022}}
