11. Magnocellular neurosecretory cells Oxytocin Affects uterine contractions in pregnancy and birth and subsequent release of breast milk Vasopressin (ADH) Controls the blood fluid and mineral levels in the body by affecting water retention by the kidneys.

19. Stress response : The hypothalamus pituitary and adrenals axis) External stress triggers CRH secretion by the hypothalamus. In turn, this signals to the pituitary to release ACTH which stimulates the adrenal gland to release cortisol. Cortisol binds to the glucocorticoid receptor ® in the pituitary and has a negative feedback effect on the release of CRH and ACTH. In addition, the cortisol-receptor complex has a positive feedback effect, promoting further receptor synthesis.
