Flashcards in 0-1 chapter 17 - hormones Deck (28):
1

melatonin

Pineal
Target tissue - hypothalamus (brain to brain - diencephalon to hypothalamus)

Effect: regulates body clock, promotes sleepiness, may involve reproduction, circadian rhythm
(More produced at night)

BRAIN/HYPOTHALMUS. - SLEEP CYCLE

2

TRH

Thyroid Releasing Hormone

Hypothalamus

Target anterior pituitary
Effect: TSH secretion

3

CRH

Corticotropin Releasing Hormone

Hypothalamus

Target anterior pituitary

Effect ACTH SECRETION

4

GnRH

Gonadotrophin Releasing Hormone

Hypothalamus

Target anterior pituitary

Effect FSH, LH Secretion

5



GHRH/GHIH

Growth Hormone Releasing/Inhibiting Hormone

Hypothalamus


Somatostatin inhibits secretion of hGH

Target anterior pituitary

Effect: Release or inhibit secretion of hGH

6

PRH/PIH

Prolactin Releasing/Inhibiting Hormone

Hypothalamus

Target anterior pituitary

Effect: promotes or suppresses release of prolactin

7

TSH

Thyroid Stimulating Hormone

Anterior Pituitary

Target - thyroid

Effect - stimulates synthesis and release of T3/T4

8

ACTH

Adrenocorticotropic Hormone

Anterior Pituitary

Target - adrenal cortex

Effect: controls production and release of cortisol

9

FSH, LH

Follicle Stimulating Hormone

Luteinizing Hormone

Anterior Pituitary

Target : gonads

Effect : release estrogen, proestergine, testosterone

10

hGH

Human Growth Hormone

Anterior Pituitary

Target - body

Effect - maintain mass, repair

11

PRL

Prolcatin

Anterior Pituitary

Target- mammary glands

Effect - initiate and maintain milk production

12

ADH

Antidiuretic Hormone

Posterior Pituitary

Target - kidneys

Effect - decrease urine

13

Oxytocin

Posterior Pituitary

Target - uterus, breast

Effect - muscle contraction

14

T3, T4

Thyroid
(T3) triiodothyronine - thyroid gland, follicular cells (source), general (target) - INCREASES METABOLISM

(T4) tetraiodothyronine - thyroid gland, follicular cells (source), general target - INCREASES METABOLISM (usually converted to T3 first)

Target - general
Effect - increase metabolism

15

Calcitonin

Thyroid(parafollicular cells) , bone tissue (target), increases calcium storage in the bone, LOWERING Ca++ LEVELS

Target bone tissue
Effect - increase calcium storage in bone

16

PTH

Parathyroid Hormone

Parathyroid
bone tissue/kidneys (target), increases calcium removal from storage in bone and produces the the active form of vitamin D (calcitrol) in the kidneys, increasing absorption of calcium via intestines and INCREASING BLOOD Ca++ LEVELS
increases osteoclasts
Target- bone/kidneys
Effect- increase blood calcium

17

Thymosin

Thymus
(educates T cells)
Target tissue- immune system
Effect- promotes formation & maturation of T cells

Large in children, begins to atrophy throughout life

Target - immune system
Effect - T cell formation/maturation

18

Epinepherine &
Norepinephrine

Adrenals - medula

Target: sympathetic effectors

Effect: enhance and prolong sympathetic effect

19

Aldosterone

Adrenals - cortex

Target : kidneys

Effect: water conservation

20

Cortisol

Adrenals - cortex

Target - all tissues

Effect : metabolism/ anti-inflammatory

21

Adrenal Androgens/Estrogens

Adrenals - cortex

Target: sex organs

Effect : sexual function

22

Insulin

Pancreas
From beta cells
Target tissues: various cells/tissues throughout the body, general
Effect - lowers blood sugar - tells cells to absorb/uptake glucose from blood to cells
If used it's energy, if not it turns to fat
INTO THE CELLS

Target : general

Effect - decrease blood sugar

23

Glucagon

Pancreas
From alpha cells
Target tissues- glycogen stored in liver/glucagon from pancreas
Effect- increases blood sugar (breaks down glycogen into glucose)

Target - liver
Effect - increase blood sugar

24

Estrogens/Progesterone

Ovaries

Target : general

Effect - monthly cycle, body shape

24

Testerone

Testes

Target - general

Effect - sperm production, male characteristics

25

Releasing and inhibiting hormones come from

HYPOTHALMUS

26

Tropic and non-tropic hormones come from

Anterior pituitary

27

Insulin is only hormone that will

Decrease blood sugar
