Human growth hormone A. Synthesized by the hypothalamus and stored/secreted by the posterior pituitary - enhances contractions of the uterus; stimulates milk ejection from mammary glands; has actions with brain that foster parental caretaking behavior toward offspring. Thyroid stimulating hormone B. Secreted by anterior pituitary - stimulates development and maturation of ovarian follicles in females; stimulates sperm production in males. C. Synthesized by anterior pituitary - increases protein synthesis, causing growth of bones and skeletal muscles, enhances lipolysis in adipose tissue, resulting in increased use of released fatty acids for ATP production by body cells.
