!Pituitary Gland - Posterior Lobe
!!Anatomy
The pituitary is the master gland of the whole ((Endocrine - System Overview|endocrine system)).The posterior lobe or neurohypophysis consists of neural tissues (or __neurosecretory cells__); which are bridged between the hypothalamus and pituitary gland. Neurosecretory cells produce store and release two hormones:

*__Antidiuretic__ (Vasopressin)
*__Oxytocin__
Function of Antidiuretic hormone (ADH) is __maintaining homeostasis__. It targets the __((Urinary - Kidneys - Collecting Tubules|Kidney Tubules))__ and their relay in the Brain Stem. The hormone helps in __reabsorbing water__ from primary urine into the ((Circulatory - Blood|blood)), thus decreases the amount of urine and concentrates it. ADH also causes water retention in the tissues during a stress-active abandonment conflict, and effects __vasoconstriction__, which increases blood pressure. It influences __male sexual behaviour__.

Target of oxytocin hormone are female ((Reproductive - Breast Overview|breasts)) and ((Reproductive - Uterus Overview|uterus)). The hormone stimulates milk release from breasts and uterus contraction during childbirth. Oxytocin seems to be a “wellness and __bonding hormone__” as it plays a role in maternal behaviors, __wound healing__, social recognition and empathy, __trust__, [https://m.medicalxpress.com/news/2015-12-hormone-oxytocin-anxiety-drug-effects.html|fear], __sexual arousal__ and orgasm. It __regulates stress__, and also works as a neurotransmitter.

Oxytocin is involved in the processes of __periinsular cortex relays__ of sexuality, social connections and belonging, as well as ((Reproductive - Uterus - Myometrium|uterus muscle)) (MB +/-) and ((Reproductive - Milk Ducts and Mamilla|breast gland ducts)) (CC -/+)

!!!Relay:
__Cerebral Cortex__ (-/+)

!!Mind:
!!!Theme:
Social bonding & reproduction, identity & thriving in community (Conflictive: not being allowed to bond, abandonment

!!!Emotions and Thoughts:
__Longing, loyalty, bonding__
*Why can't we be together?
*I miss your touch!
*This is not the right time/environment for us!
*I am left out on my own.


!!!META-Meaning:
*I trust in the universe to show me all opportunities.
*I will find the right environment to thrive.
*I can be free and connected.
!!Organ

!!!Stress Phase Symptoms:
In general stress, oxytocin is released in the brain to regulate and calm it. Thus, decrease in secretion of oxytocin by special social stress leads to low stress tolerance, __anxiety__, impaired bonding and social behaviour, a __longer birthing process__. 
ADH however acts as counterpart and is in a "social stress" phase released into the blood stream, comparable to the "excretory duct" pattern in the Cerebral Cortex. From there, it effects the ((Urinary - Kidneys - Collecting Tubules|Kidney Tubules)) and __water retention__ in the body, leading to __high blood pressure__, reduced urination, enlargement of oedema, and the will to survive under hostile conditions.

!!!Regeneration Phase Symptoms:
New regulation of hormonal balance with enhanced production and release of oxytocin creates , social interest and attention and sexual stimulation, but also less tolerance to persons outside the own community, __envy, aggression__ and [https://m.medicalxpress.com/news/2015-12-hormone-oxytocin-anxiety-drug-effects.html|anxiety]. On physical level __lowering of blood pressure__ and cortisol levels, quicker birthing process by stimulation of contractions of the uterus muscles, opening of milk ducts and __induction of lactation__, better wound healing with __reduced inflammation__.

!!!Biological Meaning:
Stress resilience is found in the __balance of belonging and social connection__, with individuality, freedom and tolerance for others. This is mirrored in the biological strategies of the territorial relays of the Cerebral Cortex (insular region) and their constellations, affecting the "hormonal scale":

!!Social
!!!Examples:
*A woman who earlier had a breast tumor with contact theme, is fearful and aggressive towards immigrants and refugees in her country.
*After a big fight and reconciliation, the partners have the best sex ever.
*A single mother looks for a community that provides her an opportunity to make a living for her children and that allows her children to thrive. She fights for acceptance as an immigrant, but has no interest in seeking a new partner. (Klapp)

!!Additional Information
Oxytocin and ADH balance each other and balance our perception of __community and individuality__: while high levels of oxytocin make us more interested and caring for our partner or group, they also make us judge and react stronger against foreigners.  ADH helps us to be cooperative in emergency, thus being capable for more acceptance.

The pituitary gland is represented by the 6th or __third eye chakra__, characterizing understanding, light and overview. 

A lack of ADH leads to enhanced urination and  much thirst, as the ((Urinary - Kidneys - Collecting Tubules|renal tubules)) do not work properly in their function of water reabsorption.This matches the diagnosis __diabetes insipidus__. The conflictive pattern can have to do with territory-marking.

!!!Constellations
While different types of mania can be related to increased levels of testosterone, depression and schizophrenia are observed together with an excess of oxytocin rather than estrogen. Vasopressin, dependent on the receptor site in the brain, relates both to social fear or to aggression, modulating social behaviour between competition and cooperation.

!!!Differential Diagnosis
__((Reproductive - Uterus - Mouth and Neck|Uterus Cervix wall))__ (CM -/+) Stress (pregnancy self-devaluation)): weakening, abortion/premature birth possible

__((Reproductive - Uterus - Myometrium|Uterus Myometrium))__ (MB +/-) Stress (wish for pregnancy): reinforcement, fibroids (can remain after regeneration)

__((Reproductive - Mammary Glands|Mammary glands))__ (CB +/-) Stress (worry, fight): enhanced secretion, lobular breast cancer; Regeneration phase: mastitis

__((Reproductive - Milk Ducts and Mamilla|Milk ducts))__ (CC -/+) Stress (loss of contact): temporary enhanced lactation, ductal ulcus-carcinoma; Regeneration phase: mastitis, ductal tumor; residual calcifications possible 

__((Urinary - Kidneys - Collecting Tubules|Kidney Collecting Tubules))__ (BS +/-) Stress (abandonment): water retention, oedema; Chronic regeneration pattern: renal insufficiency (loss of function) possible
