1

what does the body's physiologic response to stress include

increase HR, resp rate and BP

2

what can prolonged stress cause release of

cortisol (which inhibits immune response making one susceptible to illness)

3

what do endocrine disorders in children generally affect

their growth

4

what might one experience if they get their thyroid removed

hypothyroidism

5

what membrane can protein cells not easily cross

cell membrane of nonsteroidal hormones

6

what are steroids soluble in? can they cross cell membranes easily?

lipids (fats)

Yes

7

what are nonsteroidal hormones made of

amino acids and proteins that cant easily cross cell membranes

8

what produces prostaglandins

kidneys, stomach, uterus, heart and brain

9

what turns genes on or off

hormone-receptor complex for steroidal hormones

10

what does the adrenal cortex secrete?

the adrenal medulla?

aldosterone

epinephrine

11

what secretes T3&T4 along with calcitonin

thyroid

12

what secretes growth hormone, melanocyte-stimulating hormone, thyroid-stimulating hormone and more

Anterior pituitary

13

what do alpha cells of the pancreas secrete

glucagon

14

what does the posterior pituitary secrete

antidiuretic hormone & oxytocin

15

what is the luteinizing hormone released by

anterior pituitary

16

what releases parathyroid hormone (PTH)

parathyroid gland

17

what does oxytocin do

stimulate contraction of prostate & vas deferens during male sexual arousal

18

what does insulin do

decrease BS and increase protein synthesis

19

what increases BS and decreases protein synthesis

Glucagon

20

what does aldosterone stimulate the body to retain

sodium & water which helps retain water & maintain BP

21

what does the thyroid hormone increase

cells energy production, stimulate protein synthesis and speed up repair of damaged tissues

22

what lowers blood calcium lvls & raises bone calcium lvls activating osteoblast

calcitonin

23

what is the advantage of corticol decreasing protein synthesis

it also decreases inflammation which decreases pain

24

where is erythropoietin secreted and what does it do

the kidneys

stimulates blood cell production

25

where is atrial natriuretic peptide secreted and what does it do

the heart

works with ADH from adrenal cortex to help regulate BP

26

what does the pineal body release and what does it do

melatonin which regulates the biological clock linked w puberty

27

where is thymosis released from

the thymus and it promotes production of T lymphocytes

28

what does erythropoietin do

secreted from the kidneys it stimulates RBC production

29

what are circadian rhythms regulated by

melatonin

30

what happens in myxedema

thyroid gland does not produce adequate amounts of thyroid hormone

31

what is the condition where to much growth hormone is produced during childhood

gigantism

32

what is diabetes mellitus and what are lab tests for diagnosis

caused by production of too little or no insulin

urinalysis, fasting blood sugar, glucose tolerance test, high A1C

33

what is the condition where to much growth hormone is released in adults

acromegaly

34

what is cretinism

extreme form of hypothyroidism present prior to or soon after birth

35

what is Cushing's syndrome also known as

hypercortisolism (persons production of cortisol)

36

what is it called when too little growth hormone is produced in childhood

dwarfism which may be diagnosed by genetic testing and imaging studies

37

what is the disease in which a person develops antibody's that attack the thyroid gland

graves disease

38

what are symptoms of myxedema

weakness, fatigue, weight gain, dry skin, hair loss

39

what are signs and symptoms of acromegaly

enlargement of bones in entire skull, hands & feet, thickening of skin, headache, fatigue

40

what are common signs of cushings syndrome

round face, hump btwn shoulders, thin arms & legs w large abdomen

41
