what are the hormones of the anterior pituitary
TSH-Thyroid Stimulating Hormone
FSH-follicle stimulating hormone
What are the hormones of the posterior pituitary
The posterior pituatry gland is stimulated by

FSH is one of which hormone and what does it effect
effects the gonads
: ovraries or testes.
What does FSH stimulate
secretion of estrogen for women, sperm production in men and is stimulated by hypothalamus,
what is another gonadotropic hormone and what does it stiumulate

ovulation for women
: interstitial cells of the testes to secrete testosterone in men
Secretion of the LH hormone is regulated by
