1

Thyrotropin-releasing hormone

- hypothalamus
- stimulates secretion of thyroid-stimulating hormone and prolactin
- peptide

2

Corticotropin-releasing hormone

- hypothalamus
- causes release of adrenocorticotropic hormone
- peptide

3

Growth hormone-releasing hormone

- hypothalamus
- causes release of growth hormone
- peptide

4

Growth hormone inhibitory hormone (somatostatin)

- hypothalamus
- inhibits release of growth hormone
- peptide

5

Gonadotropin-releasing hormone

- hypothalamus
- causes release of lutenizing hormone and follicle-stimulating hormone

6

Dopamine or prolactin-inhibiting factor

- hypothalamus
- inhibits release of prolactin
- amine

7

Growth hormone

- anterior pituitary
- stimulates protein synthesis and overall growth of most cells and tissues
- peptide

8

Thyroid-stimulating hormone

- anterior pituitary
- stimulates synthesis and secretion of thyroid hormones (thyroxine and triiodothyronine)
- peptide

9

Adrenocorticotropic hormone

- anterior pituitary
- stimulates synthesis and secretion of adrenocortical hormones (cortisol, androgens, aldosterone)
- peptide

10

Prolactin

- anterior pituitary
- promotes development of the female breasts and secretion of milk
- peptide

11

Follicle-stimulating hormone

- anterior pituitary
- causes growth of follicles in the ovaries and sperm maturation in sertoli cells of testes
- peptide

12

Luteninzing hormone

- anterior pituitary
- stimulates testosterone synthesis in leydig cells of testes
- stimulates ovulation, formation of corpus luteum and estrogen and progesterone synthesis in ovaries
- peptide

13

Antidiuretic hormone

- posterior pituitary
- increases water reabsorption by the kidneys and causes vasoconstriction and increased blood pressure
- peptide

14

Oxytocin

- posterior pituitary
- stimulates milk ejection from breasts and uterine contractions
- peptide

15

Thyroxine (T4) and triiodothyronine (T3)

- thyroid
- increases the rates of chemical reactions in most cells, thus increasing body metabolic rate
- amine

16

Calcitonin

- thyroid
- promotes deposition of calcium in the bones and decreases extracellular fluid calcium ion concentration
- peptide

17

Cortisol

- adrenal cortex
- multiple metabolic functions for controlling metabolism of proteins, carbs, and fats
- also anti-inflammatory effects
- steroid

18

Aldosterone

- adrenal cortex
- increases renal sodium reabsorption, potassium secretion, and H ion secretion
- steroid

19

Norepinephrine, epinephrine

- adrenal medulla
- same effects as sympathetic stimulation
- amine

20

Insulin (beta cells)

- pancreas
- promotes glucose entry in many cells, controls carb metabolism
- peptide

21

Glucagon (alpha cells)

- pancreas
- increases synthesis and release of glucose from liver into the body fluids
- peptide

22

Parathyroid hormone

- parathyroid
- controls serum calcium ion concentration by increasing calcium absorption by the gut and kidneys and releasing calcium from bones
- peptide

23

Testosterone

- testes
- promotes development of male repro system and secondary sex characteristics
- steroid

24

Estrogens

- ovaries
- promotes growth and development of female repro system, female breasts, female secondary sex characteristics
- steroid

25

Progesterone

- ovaries
- stimulates secretion of uterine milk by the uterine endometrial glands and promotes development of secretory apparatus of breasts
- steroid
