1

Thyroid-stimulating hormone (TSH)

stimulates the secretion of the thyroid hormone
tropic hormone
anterior pituitary

2

Andrenocorticotropic hormone (ACTH)

stimulates the secretion of the adrenal cortex hormones
tropic hormone
anterior pituitary

3

Follicle-stimulating hormone (FSH)

Female: stimulates development of ovarian follicles and secretion of estrogens
Male: stimulates seminiferous tubules of testes to grow and produce sperm
Tropic hormone
Anterior Pituitary

4

Luteinizing Hormone (LH)

Female: stimulates maturation of ovarian follicle and ovum, secretion of estrogen, triggers ovulations, development of the corpus luteum
Male: stimulates interstitial cells of the testes to secrete testosterone
Tropic Hormone
Anterior Pituitary

5

Growth Hormone (GH)

stimulates growth in all organs, mobilizes food molecules, causing an increase in blood glucose concentration
Anterior Pituitary

6

Prolactin

Simulates breast development during pregnancy and milk secretion after
Anterior Pituitary

7

Antidiuretic hormone (ADH)

Stimulates retention of water by the kidneys
Posterior Pituitary

8

Oxytocin

Stimulates the uterine contractions at the end of pregnancy and the release of milk into the breast ducts
Posterior Pituitary

9

Releasing Hormones

Stimulate the anterior pituitary to release hormones
Hypothalamus

10

Inhibiting hormones

Inhibit/restrain the anterior pituitary's secretion of hormones
Hypothalamus

11

Thyroxine (T4) Triiodothyronine (T3)

stimulate the energy metabolism of all cells
Thyroid

12

Calcitonin

Inhibits the breakdown of bone causing a decrease in blood calcium concentration
Thyroid

13

Parathyroid hormone (PTH)

Stimulates the breakdown of bone causing an increase in blood calcium concentration
Parathyroid

14

Mineralocorticoids:aldosterone

Regulate electrolyte and fluid homeostasis
Adrenal cortex

15

Glucocorticoids:Cortisol

Stimulate gluconeogenesis causing an increase in blood glucose concentration also have an antiinflammatory and anti-immunity antiallergy effects
Adrenal cortex

16

Sex hormones (androgens)

Stimulate sexual drive in the female but have negligible effects in the male
Andrenal cortex

17

Epinephrine

Prolong and intensify the sympathetic nervous response during stress
Adrenal Medulla

18

Glucagon

Stimulate liver glycogenolysis causing an increase in blood glucose concentration
Pancreatic islets

19

Insulin

Promotes glucose entry into all cells causing a decrease in blood glucose concentration
Pancreatic Islets

Estrogens

Promotes development and maintenance of female sexual characteristics
Ovary

21

Progesterone

Promotes conditions required for pregnancy
Ovary

22

Testosterone

promotes development and maintenance of male sexual characteristics
Testes

23

Thymosin

Promotes development of immune system cells
thymus

24

Melatonin

Inhibits tropic hormones that affect the ovaries and may be involved in the body's internal clock sleep cycle
Pineal Gland

25

Atrial natriuretic hormone (ANH)

regulates fluid and electrolyte homeostasis
Heart
