| | Pituitary Tumors |
 | | Pituitary adenomas are benign tumors (meaning that they are non-cancerous and do not travel to other parts of the body) that arise exclusively within the anterior pituitary. | | | Pituitary tissue is acquired through biopsy at the time of surgical removal. | | | Surgical therapy for these tumors usually will not improve survival because the patient has cancer elsewhere in his or her body. |

| | The most convincing data that the posterior pituitary can influence anterior pituitary function comes from animal studies in which the posterior pituitary is surgically removed. | | | Since their concentration in the posterior pituitary is low, release into the peripheral circulation for action at a distant locus seems remote. | | | There is considerable evidence, however, that some of the peptides in the posterior pituitary are destined for transport to the anterior pituitary via the short portal vessels, thereby utilizing the posterior pituitary as an accessory median eminence. |

Non-visualisation of the stalk is associated with lack of anterior pituitary function while visualization of the stalk is associated with preservation of some anterior function[2]. |

| | Treatment of this condition is with analogues of AVP such as desamino D-arginine administered subcutaneously or by nasal spray. | | | It leads to water retention, serum hypo-osmolality, hyponatraemia and high urine osmolality.These effects cause symptoms of headache, apathy, nausea and vomiting, impaired conciousness and can be fatal in extreme cases. | | | Underproduction of AVP results in the condtion of diabetes insipidus, which is neurogenic in origin (rather than due to failure of the kidneys to respond to AVP) and can result from a pituitary tumour, head traumas or surgery which damages the pituitary gland and hypothalamus.Sometimes it is due to autoimmune destruction of the AVP neurons. |

| | In contrast, the posterior pituitary (neurohypophysis) comprises axons originating in neuronal cell bodies located in the hypothalamus. | | | The pituitary gland (hypophysis) is no longer considered the "master gland." The hypothalamus is the final common pathway that receives input from virtually all other areas of the CNS and directs input to the pituitary. | | | An intermediate lobe located between the anterior and posterior lobes is present in some species and during fetal development in humans, but its cells are scattered throughout the anterior and posterior lobes in adult humans, in whom no specific intermediate gland is recognizable. |

| | Posterior pituitary - Wikipedia, the free encyclopedia |
| | The posterior pituitary (also called the neurohypophysis) comprises the posterior lobe of the pituitary gland and is part of the endocrine system. | | | It consists mainly of neuronal projections (axons) extending from the supraoptic and paraventricular nuclei of the hypothalamus that secrete peptide hormones into the capillaries of the hypophyseal circulation. | | | Hormones known classically as posterior pituitary hormones are synthesized by the hypothalamus. |
