- 2 fused glands (anterior and posterior)
- Extends down from the brain – connected by thin stalk
Anterior Pituitary Gland (adenohypophysis)
- Epithelial origin – embryonic tissue that formed the roof of the mouth
- 6 hormones – all controlled by hypothalamus
- Prolactin, TSH, ACTH, GH, FSH, LH
- A.p. hormones control growth, metabolism, and reproduction
- Prolactin – milk production
- GH (somatotropin)
- Metabolism of many tissues
- Activates hormone production by liver
- FSH, LH – gonadotrophins (ovaries and testes)
- TSH (thyrotropin) – controls hormone synthesis + secretion in the thyroid gland
- ACTH (corticotrophin) – acts on adrenal cortex à cortisol
