1) Cortisol
2) Aldosterone
3) Epinephrine

Front 11

What does Cortisol (Steroid hormone) do?

Back 11

· Stress hormone released in response to psycological challenges.
· Produced in the adrenal cortex

Front 12

What does Aldosterone (Steroid hormone) do?

Back 12

· Acts on Distal Tubules to Cause Reabsorption of Sodium and Water
· Produced in the adrenal cortex

Front 13

What are two other names for Adrenaline?

Back 13

1) Epinephrine
2) "Fight or Flight" Hormone

Front 14

What does Epinephrine (Amine hormone) do?

Back 14

Raises blood glucose level, increases metabolic activity

· Produced in the adrenal medulla

Front 15

What are the 2 pancreatic hormones?

Back 15

1) Insulin (protein hormone)
2) Glucagon (protein hormone)

Front 16

What does Insulin do?

Back 16

Lowers blood sugar in response to high blood glucose levels. Does so by stimulating Glycogen formation (sugar storage)

Front 17

What does Glucagon do?

Back 17

Stimulates conversion of Glycogen to Glucose. Raises blood sugar

Front 18

What does PTH (peptide hormone) do?

Back 18

Increases concentration of Calcium Ions to assist in process of bone maintenance.

Front 19

What are the 3 sex hormones?

Back 19

1) Progesterone
2) Estrogen
3) Testosterone

Front 20

What does Progesterone (Steroid hormone) do?

Back 20

Regulates menstrual cycle and pregnancy

Front 21

What does Testosterone (Steroid Hormone) do?

Back 21

Stimulates sex characteristics in men

Front 22

What does Estrogen (steroid hormone) do?

Back 22

Stimulates sex characteristics in women.
Induces release of LH.

Front 23

What are the 2 thyroid hormones?

Back 23

1) Calcitonin
2) Thyroxine

Front 24

What does Calcitonin (Peptide Hormone) do?

Back 24

Lowers concentration of Calcium Ions. Works against PTH.

Front 25

What does Thyroxine (Amine hormone) do?

Back 25

Stimulates metabolic activites

Front 26

What is an example of negative feedback in hormone secretion?

Back 26

Insulin is secreted by the pancreas to inhibit the production of glucose when sugar blood levels are too high. When they drop to or below the optimum level, the production of insulin is inhibited.

Front 27

What is an example of positive feedback in hormone secretion?

Back 27

Estrogen is released as a result of FSH in females. It stimulates the release of LH which acts on the ovaries to stimulate further secretion of estrogen.

Front 28

What is negative feedback?

Back 28

Hormone acts to directly or indirectly inhibit further secretion of its own hormone kind.

Front 29

What is positive feedback?

Back 29

Hormone acts to directly or indirectly cause increased secretion of itself.

Front 30

Front 31

What does LH do? (2 func.)

Back 31

· Stimulates ovulation and formation of corpus luteum.
· Stimulates synthesis of estrogen and progesterone.

Front 32

What does TSH do?

Back 32

· Stimulates synthesis and secretion of thyroid hormones that regulate metabolism

Front 33

What do Growth Hormones (protein hormone) do?

Back 33

Stimulate protein synthesis and general growth in body

Front 34

What does PRL stand for?

Back 34

Prolactin (protein hormone)

Front 35

What is Melatonin and from what gland does it originate?
