1

What hormones are produced in the hypothalamus?

Oxytocin
Vasopressin (ADH)
Releasing hormone (RH)
Inhibiting hormone (IH)

2

Oxytocin:

(produced in hypothalamus)
-initiates labor
-stimulates mammary glands to release milk
-stimulates uterine contractions in activities other than labor

3

Vasopressin:

(produced in hypothalamus)
decreases urine output by increasing DCT and collecting duct permeability

4

Releasing hormones:

(produced in hypothalamus)
stimulate release of anterior pituitary hormones

5

Inhibiting hormones:

(produced in hypothalamus)
inhibit release of anterior pituitary hormones

6

Oxytocin and vasopressin are manufactured in the hypothalamus but released where?

posterior pituitary

7

Anterior pituitary gland hormones:

Growth hormone (GH)
Thyroid stimulating hormone (TSH)
Adrenocorticotropic hormone (ACTH)
Follicle-stimulating hormone (FSH)
Lutenizing hormone (LH)
Melanocyte-stimulating hormone (MSH)
Prolactin (PRL)

8

Growth hormone (GH):

(produced & released in anterior pituitary)
-regulates growth
-affects protein, fat, and carb metabolism

9

Thyroid stimulating hormone (TSH):

(produced & released in anterior pituitary)
-controls secretion of thyroxin

10

Adrenocorticotropic hormone (ACTH):

(produced & released in anterior pituitary)
controls secretion of hormones released by adrenal cortex, specifically glucocorticoids

11

Follicle-stimulating hormone (FSH):

(produced & released in anterior pituitary)
-females: stimulates maturation of egg cells
-males: stimulates nurse cells for sperm maturation

12

Lutenizing hormone (LH):

(produced & released in anterior pituitary)
females: stimulates release of ovum by ovary
males: stimulates secretion of testosterone by testes

13

Prolactin (LH):

(produced & released in anterior pituitary)
stimulates milk production

14

Melanocyte-stimulating hormone (MSH):

(produced & released in anterior pituitary)
along with ACTH, affects pigment release in skin

15

Pineal gland hormones:

melatonin

16

Melatonin:

(from pineal gland)
amino acid derivative thought to have connection with regulating sleep

17

Thymus gland hormones:

Thymosin
Thymus humeral factor
Thymopoietin

18

Thymosin
Thymus humeral factor
Thymopoietin

convert embryonic lymphocytes into T-cells

19

Thyroid gland hormones:

Thyroxin
Calcitonin

20

Thyroxin:

(from thyroid gland)
regulates rate of metabolism

21

Calcitonin:

(from thyroid gland)
decreases levels of calcium in the blood by inhibiting osteoclasts and increasing calcium excretion

22

What is partially antagonistic to parathyroid hormones?

calcitonin

23

Parathyroid gland hormones:

Parathyroid hormone (PTH)

24

Parathyroid hormone (PTH):

(from parathyroid hormone)
-raises the level of calcium in the blood by inhibiting osteoblasts and promoting osteoclasts and promoting calcium reabsorption by the kidneys

25

What is partially antagonistic to calcitonin?

parathyroid hormones

26

Adrenal gland hormones:

Cortex:
mineralcorticoids
glucocorticoids
androgens
Medulla:
adrenaline
noradrenaline

27

Mineralcorticoids:

(from the cortex of the adrenal gland)
regulate sodium retention and potassium loss (e.g. aldosterone)

28

Glucocorticoids:

(from the cortex of the adrenal gland)
act as anti-inflammatory agents; affect metabolism of food

29

Androgens:

(from the cortex of the adrenal gland)
regulates control over rapid growth spurts in preadolescents

30

Adrenaline:

(from the medulla of the adrenal gland)
increases heart rate and blood pressure

31

Noradrenaline:

(from the medulla of the adrenal gland)
constricts arterioles

32

Pancreas hormones:

glucagon
insulin

33

Glucagon:

(from the pancreas)
from alpha cells of pancreatic islets, raises blood glucose level

34

Insulin:

(from the pancreas)
from beta cells of pancreatic islets, lowers blood glucose level

35

Ovary hormones:

estrogens
progesteron + estrogens

36

Estrogens:

(from the ovary)
stimulate development of female sex organs and sexual characteristics

37

Progesterone + estrogens:

(from the ovary)
-regulate menstrual cycle
-maintain pregnancy in presence of developing embryo or fetus

38

Testes hormones:

testosterone

39

Testosterone:

(from the testes)
stimulate development of male sex organs, secondary sexual characteristics, and behavioral features
-functions of testosterone and its secretion is tied to secretion of LH from anterior pituitary gland
