Releasing hormone

2

RIH

Release inhibiting hormone

3

oxytocin Posterior pituitary

4

ADH

Antidiuretic hormone (Posterior pituitary)

5

ACTH

Adrenodocorticotrpic hormone

6

CRH

Coticotropin releasing hormone

7

TSH

Thyroid stimulating hormone (Thyrotropin)

8

TRH

Thyrotropin releasing hormone

9

FSH

Follicle Stimulating Hormone

10

LH

Lutenizing hormone

11

Gonadotropin releasing hormone

12

GH

Growth hormone

13

Growth hormone releasing hormone

14

GHRIH

Growth hormone release inhibiting hormone

15

PIH

Prolactin inhibiting hormone

16

PRL

Prolactin

17

MEL

Melatonin

18

TH

Thyroid hormone.

19

T3

Triioldothyronine

20

T4

Thyroxine

21

PTH

Parathyroid glands

22

DHEA

Adrenal androgens gonadocorticoids. From Zona Reticularis

23

DHEAS

Adrenal androgens gonadocorticoids. From Zona Reticularis

24

Endocrine cell communication

Across long distances.
Hormones in blood
target cell receptor specificity

25

Neurocrine cell communication

Across short distances. Sending cell is a neuron, receiving cell is a neuron, muscle or gland.

26

Autocrine

Produces and binds chemicals to self that can cause change.

27

Paracrine

short distance.
message to all cells in immediate area.

28

Endocrine vs. Exocrine glands

Endo: synthesize hormones, secrete hormones into blood.
Exo: contain ducts, secrete products onto epithelial surface.

29

Nervous vs. Endocrine

Nervous: Fast control, chemical messages called neurotransmitters. Target cell specificity. Synapses (Short communications). Fast transmissions, fast removal, electric signals.
Endocrine: Slow, chemical messages called hormones, target cell specificity, communication over long distances, sow transmission, slow removal.

30

Names for Anterior pituitary

pars distalis, adenohypophysis,

31

Names for posterior pituitary

pars nervosa, neurohypothesis

32

Portal system

hypothalamo-hypophyseal system

33

Targets of TH

All cells: Protein anabolism, increase metabolic rate.
Liver: gluconeogenesis, glycogenolysis.
Adipose: lipolysis

34

Targets of GH

Liver: IGF, gluconeogenesis, glycogenesis
Adipose: Lipolyisis
All Cells: protein anabolism

35

Targets of Cortisol

Liver: gluconeogensis ( From aa)
Adipose; Lipolysis
All cells: Protein catabolism

36

Targets of glucagon

(too little Glucose in blood)
Liver: gluconeogenesis, glycogenolysis
Adipose: lipolysis

37

Targets of insulin

All cells: protein anabolism, increase uptake of glucose.
Adipose: lipogenesis
Liver: glycogenesis

38

Layers of adrenals from bottom to top

Medulla, zona Reticularis, Zona fasciculata, zona glomerulosa

39

Zona glomerulosa

stimulated by Ang II, releases Aldosterone

40

Zona Fasciculata

Stimulated by ACTH, releases Cotisol

41

Zona Retiularis

Stimulated by ACTH, releases DHEA, DHEAS

42

Tropic hormones

released from anterior pituitary

43

up regulation

target cells increase number of receptors in increase responsiveness

44

down regulation

target cells decrease number of receptors to decrease responsiveness

45

synergistic

hormones work together to produce greater effect

46

permissive

one hormone permits another hormone to have an effect

47

Antagonistic

hormones have opposite effect
