Answer 1

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

Question 2

Oxytocin:

Answer 2

(produced in hypothalamus)

• initiates labor
• stimulates mammary glands to release milk
• stimulates uterine contractions in activities other than labor

Question 3

Vasopressin:

Answer 3

(produced in hypothalamus)

decreases urine output by increasing DCT and collecting duct permeability

Question 4

Releasing hormones:

Answer 4

(produced in hypothalamus)

stimulate release of anterior pituitary hormones

Question 5

Inhibiting hormones:

Answer 5

(produced in hypothalamus)

inhibit release of anterior pituitary hormones

Question 6

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

Answer 6

posterior pituitary

Question 7

Anterior pituitary gland hormones:

Answer 7

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

Question 8

Growth hormone (GH):

Answer 8

(produced & released in anterior pituitary)

• regulates growth
• affects protein, fat, and carb metabolism

Question 9

Thyroid stimulating hormone (TSH):

Answer 9

(produced & released in anterior pituitary)

-controls secretion of thyroxin

Question 10

Adrenocorticotropic hormone (ACTH):

Answer 10

(produced & released in anterior pituitary)

controls secretion of hormones released by adrenal cortex, specifically glucocorticoids

Question 11

Follicle-stimulating hormone (FSH):

Answer 11

(produced & released in anterior pituitary)

• females: stimulates maturation of egg cells
• males: stimulates nurse cells for sperm maturation

Question 12

Lutenizing hormone (LH):

Answer 12

(produced & released in anterior pituitary)

females: stimulates release of ovum by ovary
males: stimulates secretion of testosterone by testes

Question 13

Prolactin (LH):

Answer 13

(produced & released in anterior pituitary)

stimulates milk production

Question 14

Melanocyte-stimulating hormone (MSH):

Answer 14

(produced & released in anterior pituitary)

along with ACTH, affects pigment release in skin

Question 15

Pineal gland hormones:

Answer 15

melatonin

Question 16

Melatonin:

Thymus gland hormones:

Answer 17

Thymosin
Thymus humeral factor
Thymopoietin

Question 18

Thymosin
Thymus humeral factor
Thymopoietin

Answer 18

convert embryonic lymphocytes into T-cells

Question 19

Thyroid gland hormones:

Answer 19

Thyroxin

Calcitonin

Question 20

Thyroxin:

Answer 20

(from thyroid gland)

regulates rate of metabolism

Question 21

Calcitonin:

Answer 21

(from thyroid gland)

decreases levels of calcium in the blood by inhibiting osteoclasts and increasing calcium excretion

Question 22

What is partially antagonistic to parathyroid hormones?

Answer 22

calcitonin

Question 23

Parathyroid gland hormones:

Answer 23

Parathyroid hormone (PTH)

Question 24

Parathyroid hormone (PTH):

Answer 24

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

Question 25

What is partially antagonistic to calcitonin?

Answer 25

parathyroid hormones

Question 26

Adrenal gland hormones:

Answer 26

``` Cortex: mineralcorticoids glucocorticoids androgens Medulla: adrenaline noradrenaline ```

Question 27

Mineralcorticoids:

Answer 27

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

Question 28

Glucocorticoids:

Answer 28

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

Question 29

Androgens:

Answer 29

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

Question 30

Adrenaline:

Answer 30

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

Question 31

Noradrenaline:

Answer 31

(from the medulla of the adrenal gland) | constricts arterioles

Question 32

Pancreas hormones:

Answer 32

glucagon | insulin

Question 33

Glucagon:

Answer 33

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

Question 34

Insulin:

Answer 34

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

Question 35

Ovary hormones:

Answer 35

estrogens | progesteron + estrogens

Question 36

Estrogens:

Answer 36

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

Question 37

Progesterone + estrogens:

Answer 37

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

Question 38

Testes hormones:

Answer 38

testosterone

Question 39

Testosterone:

Answer 39

(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
