Pitutary |
Hypophysis |
|
|
Pitutary is made of: |
Anterior: Adenohypophysis Posterior: Neurohypophysis |
|
|
Neurohypophysis consists of: |
axons from the cell body that form the paraventricular nucleus and supraoptic nucleus |
|
|
Neurohypophysis hormones |
ADH (antidiruetic hormone), Oxytocin |
|
|
Adenohypophysis hormones |
TSH (Thyroid Stimulating Hormone), LH (Lutenizing Hormone), GH (Growth Hormone), ACH (Adrenal Corticotrophic Hormone), Prolactin (PRL)
|
|
|
ADH (Anitdiuretic Hormone) |
Maintains correct water (liquid) levels in the body to prevent over consumption or dehydration; regulated by osmoreceptors, pain, low b.p, nicotine, morphine |
|
|
Oxytocin |
Contraction stimulating hormone; triggers the ejection of milk when the female body contains prolactin post child birthing; positive feedback mechanism; promotes a nurturing 'touch' and 'cuddly desires' |
|
|
GH (Growth Hormone) |
Metabolizes fats for transport, increases blood level of fatty acid; breaks down glycogen into glucose; increases b.g. levels, considered an anti-insulin hormone
|
|
|
TSH (Thyroid Stimulating Hormone) |
TRH triggers release; stimulates normal development and secretion of the thyroid
|
|
|
ACH (Adrenal Corticotropic Hormone) |
Releases corticosteriod hormones to resis stresses; triggered by fever, low b.g., anything stressful to the body |
|
|
LH (Lutenizing Hormone) |
A gonadotropin, regulates gonads and gonadal hormone production; triggers ovulation and testosterone production; GnRH controls LH
|
|
|
PRL (Prolactin) |
Stimulates milk production in mothers; dopamine inhibits this stimulant; many hormones trigger PRL, as well as infant suckling |
