Endocrine gland

Ductless glands that secrete hormones

1

Ecdysone

Hormone
Early development of insects

2

Brain hormone

Made in hypothalamus

3

Pheromones

Hormones that act between different organisms

4

Juvenile hormones

Inhibits ecdysone and prevents insects from maturing too quickly

5

Glucocorticoids

Steroid hormone
Regulates glucose level

6

Mineralcorticoids

Steroid hormones
Salt and water balance
Aldosterone

7

Thyroid gland

Growth development metabolic rate

8

Thyroxin

Secreted by thyroid
Oxygen consumption

9

Hypothyroidism

Not enough thyroid hormone is made

10

Hyperthyroidism

Too much thyroid hormone made

11

Calcitonin

Lowers calcium level

12

Parathyroid

Glands Located near thyroid
Secrete thyroid hormones

13

Estrogen

Female sex hormone

14

Amine

Neurotransmitter in plants and animal

15

cAMP

Second messenger
Mediates actions between hormones

16

Protein based hormones

Hydrophilic and not lipid soluble so have to bind to receptor proteins in cell membrane
Trigger secondary messenger

17

Lipid based hormones

Hydrophobic and lipid soluble so bind to receptor proteins in cytoplasm and nucleus
Transcription factors that turn on genes

18

Kinase cascade

Phosphate group transfers

19

G proteins

Second messengers activated by receptor proteins

20

Anterior pituitary

FSH LH ACTH growth hormone TSH prolactin
Growth, ect.

21

Posterior pituitary

Oxytocin vasopressin
Uterine contraction, kidney water absorption

22

Thyroid

Thyroid hormone calcitonin
Metabolic rate, lowers calcium level

23

Parathyroid

Parathyroid hormone
Increase blood calcium

24

Adrenal cortex

Alsosterone
Increases na and h2o reabsorption in kidneys

25

Adrenal medulla

Epinephrine nopinephrine
Increase blood glucose and heart rate

26

Pancreas

Insulin glucagon
Decrease blood sugar, increase sugar

27

Ovaries

Estrogen progesterone
Sex characteristics and endometrial lining

28

Testes

Testosterone
Sex characteristics and spermatogenesis
