Posterior Pituitary
 ADH
 Oxytocin- release by mechanic stimulation of uterus, cervix, nipples
 Causes smooth muscle contraction of uterus
o For child birth
 Causes milk ejection from lactating women
Tropic Hormones
 Control release of other hormones
o (ex: Thyroid stimulating hormone (TSH) triggers release of thyroid
hormone from thyroid gland)
 Allow for multiple steps
o Aids in regulation (tine tuning)
Anterior Pituitary
 TSH (thyroid stimulating hormone)
o Released when body temp drops for a prolonged period
o Released daily in tonic amounts
o Caused thyroid gland to release thyroid hormone
 (GH) growth hormone
o Stimulates bone & muscle growth
o Changes metabolism increase fat burning, decrease glucose burning
o Released with increased stress
o Released daily at tonic (constant, continuous) levels
Too little GH  Dwarfism
Too much GH  acromegly “Gigantism”
