Flashcards in endocrine system (hormones) Deck (28):
1

oxytocin

S: posterior pituitary
T: mammary gland, uterus
action/function: contractions/milk production

2

ADH- Antidiuretic Hormone

S: P pituitary
T: kidneys
increases reabsorption of water in kidneys

3

GH- growth hormone

S: Anterior pituitary
T: bones, muscles
causes elongation in bones - ex) epiphyseal plates

4

PRL - Prolactin

S: A Pituitary
T: mammary gland
milk production

5

FSH- Follicle Stimulating Hormone

S: A pituitary
T: testis, ovaries
production of sperm

6

LH- Luteinizing Hormone

S: A pituitary
T: testis/ovaries
production of ova

7

TSH- Thyroid Stimulating Hormone

S: A Pituitary
T: Thyroid
stimulates the thyroid to secrete T4 (thyroxin) and T3 (triiodothyronine)

8

ACTH- Adrenocorticotropic Hormone

S: A Pituitary
T: adrenal cortex
causes increase in synthesis and secretion of hormones from adrenal cortex
ex) glucocorticoids

9

Melatonin

S: Pineal gland
T: body
circadian rhythms (ex: sleeps cycles, growth spurts, etc)

10

T4 (Thyroxine)

S: Thyroid
T: Bone, body
increases cellular metabolism

11

T3 (Triiodothyronine)

S: thyroid
T: body, bone
body processes including temperature, growth, and heart rate

12

Calcitonin

S: thyroid
T: bone
lowers blood calcium

13

PTH- Parathyroid Hormone

S: Parathyroid
T: Bone
increases amount of calcium in blood

14

Thymosin

S: Thymus
T: Thymus
T cell development

15

Epinephrine

S: Medulla is adrenal glans
T: Heart, BV, liver
increases glucose in blood stream
fight for flight response

16

Norepinephrine

S: medulla of adrenal gland
T: heart, BV, liver
increases glucose in blood stream, flight or fight response

17

Glucocorticoids

S: adrenal gland
T: body, kidney
increases blood glucose

18

Mineralocorticoids

S: Adrenal Gland
T: Kidney
increases reabsorption if sodium and excretion of potassium
ex) aldosterone

19

Insulin

S: pancreas
T: body, glucose
lowers blood glucose, body cells use it for fuel, liver turns it to glycogen

20

Glucagon

S: pancreas
T: Liver
raises blood sugar

21

Androgens (Testosterone)

S: testis
T: testis, liver
spermatogenesis, secondary sex characteristics

22

Estrogens

S: ovaries
T: uterus, body
menstrual cycle, secondary sex characteristics

23

Progesterones

S: ovaries
T: ovary, uterus
uterine lining growth, pregnancy

24

auxin

stem elongation, promotion of vascular tissue growth, suppression of lateral buds

shoot apical meristems

25

cytokins (kinetin)

with auxin, stimulation of cell division and determination of course if differentiation

produced in roots and transported from there

26

gibberellins

stem and internode elongation; mobilization of enzymes during seed germination

-apical portions of roots and shoots

27

ethylene

controls abcission of leaves, flowers, fruits; retardation of lateral bud elongation; hastening of fruit ripening

leaves, stems, young fruits

28

abscisic acid

suppression of bud growth; important role in stomata opening; promotion of leaf senescence

-nature leaves, fruits, root caps
