This is the PDF version of our powerpoint presentation about the Hypothalamus, its function, what hormones it secretes and its main role in our body. This also has info about the Pituitary Gland, the hormones it releases and its function in our body.

8. PITUITARY GLAND
• Controls other endocrine glands
and body’s hormonal response to
environment
• Has 2 parts: anterior and posterior

9. PITUITARY GLAND
•

11. PITUITARY GLAND
• Secrete human growth hormone (hGH),
aka somatotropin, which stimulates tissues
to secrete hormones that stimulate body
growth and regulate metabolism.

12. PITUITARY GLAND
• Secrete follicle-stimulating hormone (FSH) and
luteinizing hormone (LH), which both act on the
gonads. They stimulate the secretion of estrogen
and progesterone, maturation of egg cells in the
ovaries, and stimulate sperm production and
secretion of testosterone in the testes.

13. PITUITARY GLAND
• Secrete prolactin (PRL), which
initiates milk production in the
mammary glands.

14. PITUITARY GLAND
• Secrete adrenocorticotropic hormone
(ACTH), which stimulates the adrenal cortex
to secrete glucocorticoids (like cortisol). Also
secretes melanocyte-stimulating hormone
(MSH).

15. PITUITARY GLAND
• Secrete thyroid-stimulating hormone
(TSH), which controls secretions of
the thyroid gland.

16. • Human-growth hormone (hGH)
- Tissues
- Stimulates tissue growth in the liver, muscles, bones, as
well as protein synthesis, tissue repair, and elevation of
blood glucose levels.
• Thyroid-stimulating hormone (TSH)
- Thyroid gland
- Stimulates thyroid gland to secrete thyroid hormones.

17. • Follicle-stimulating hormone (FSH)
- Ovaries and testes (gonads)
- Stimulates development of oocytes (immature
egg cells) and secretion of estrogen in females;
stimulates sperm production in the testes in
males.

18. • Luteinizing hormone (LH)
- Ovaries and testes (gonads)
- Stimulates secretion of estrogen and
progesterone, including during ovulation, in
females; stimulates testes to produce
testosterone in males.

19. • Prolactin (PRL)
- Mammary glands
- Stimulates milk production.
• Adrenocorticotropic hormone (ACTH)
- Adrenal cortex
- Stimulates secretion of glucocorticoids (cortisol) by the
adrenal cortex during the body’s response to stress.

20. • Melanocyte-stimulating hormone
(MSH)
- Brain
- When in excess, can cause darkening of the skin;
may influence brain activity (its exact role
unknown—there is very little MSH in humans).

21. 2. Posterior Lobe
(Neurohypophysis)
•This lobe stores and
releases only two
hormones

22. Oxytocin (OT), aka the "love" drug
• Secretes in response to uterine
distention and stimulation of the
nipples.
• Stimulates smooth muscle
contractions of the uterus during
childbirth, as well as milk ejection in
the mammary glands.

23. Antidiuretic hormone (ADH), or
vasopressin
• Secretes in response to dehydration, blood
loss, pain, stress; inhibitors of ADH secretion
include high blood volume and alcohol.
• Decreases urine volume to conserve water,
decreases water loss through sweating,
raises blood pressure by constricting
arterioles
