• The posterior pituitary is neural tissue and consists only of the distal axons of the hypothalamic magnocellular neurons that make up the neurohypophysis. • The control of hormone synthesis is at the level of transcription. Stimuli for secretion of vasopressin or oxytocin also stimulate transcription and increase the messenger ribonucleic acid (mRNA) content in the magnocellular neurons. • The physiologic regulation of vasopressin synthesis and secretion involves two systems: osmotic and pressure/ volume. • Diabetes insipidus is a disorder of a large volume of urine (diabetes) that is hypotonic, dilute, and tasteless (insipid). • The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is produced when plasma levels of arginine vasopressin (AVP) are elevated at times when the physiologic secretion of vasopressin from the posterior pituitary would normally be osmotically suppressed.
