Function
The cell bodies produce a peptide hormone: anti-diuretic hormone.
In the cell bodies, the hormones are packaged in large, membrane-bound vesicles which are transported down the axons to the nerve endings. The secretory granules are also stored in packets along the axon called Herring bodies.
Similar magnocellular neurons are also found in the paraventricular nucleus.
