Study Notes
- Posterior pituitary gland stores and secretes hormones produced by hypothalamus.
- Paraventricular nuclei produce oxytocin, supraoptic nuclei produce ADH.
- Oxytocin stimulates uterine contractions and dilation of cervix during childbirth.
- Oxytocin also plays a role in milk ejection reflex and parent-newborn bonding.
- ADH is released in response to high blood osmolarity.
- ADH increases epithelial permeability to water, allowing increased water reabsorption in kidneys.
- ADH is also known as vasopressin, can cause constriction of blood vessels.
- Release of ADH is controlled by negative feedback loop.
- Alcohol inhibits release of ADH, causing increased urine production.
- Diabetes insipidus is characterized by chronic underproduction of ADH.
