Flashcards in Endocrine Deck (29)
1

cell surface receptor

for mostly water soluble hormones embedded in plasma membrane and initiates signal transduction pathways

2

water soluble hormones

proteins and peptides; amines derived from amino acids; triggers signal transduction and response in cytoplasm or gene transcription

3

non water soluble hormones

steroids; lipid soluble binds to signal receptor(commonly transcription factor) in cytoplasm or cell

4

paracrine signaling

chemical compounds that are local regulators, not hormones

5

peptide local regulator

cytokines- immune response; growth factor- cell proliferation and differentiation

6

nitric oxide

local regulator when blood oxygen level falls, NO secreted by endothelial cells in blood vessel walls

7

prostaglandins

local regulator, modified fatty acids; inflammatory response

8

hypothalamus gland

sends hormones to posterior pituitary and produces hormones that regulate anterior pituitary

9

posterior pituitary

oxytocin and antidiuretic hormone

10

anterior pituitary

growth, thyroid stimulating, follicle stimulating hormones

11

thyroid gland

calcitonin- lowers blood calcium level

12

parathyroid gland

parathyroid hormone- raises blood calcium level

13

pancreas

insulin- lowers blood glucose; glucagon- raises blood glucose

14

glucagon

raises blood glucose level by liver break down of glycogen releasing into blood

15

adrenal gland

sits on kidney and produces epinephrine, and glucocortcoids

16

androgens

produced in testes

17

estrogens/progesterones

produced in ovaries

18

tropic hormones

hormones that regulate the function of endocrine organs

19

insulin

lowers blood glucose by cells and liver taking up glucose

20

catecholamines

epinephrine and norepinephrine affect fight or flight stress

21

epinephrine response

stronger effect on heart and metabolic rates

22

norepinephrine

strong effect on sustaining blood pressure

23

corticosteroids

glucocorticoids and mineralocorticoids- helps maintain stress over extended period of time

24

androgen hormones

main being testosterone which is important for male development

25

estrogen hormones

main being estradiol for female development

26

progestin hormones

progesterone is important for uterine development

27

brain hormone

insect brain; stimulates release of ecdysone from prothoracic glands

28

ecdysone

promotes molting and development of adult characteristics; change from caterpillar to butterfly

29

juvenile hormone

secreted by corpora allata behind insect brain
