1) Cortisol
2) Aldosterone 3) Epinephrine |
|
What does Cortisol (Steroid hormone) do?
|
· Stress hormone released in response to psycological challenges.
· Produced in the adrenal cortex |
|
What does Aldosterone (Steroid hormone) do?
|
· Acts on Distal Tubules to Cause Reabsorption of Sodium and Water
· Produced in the adrenal cortex |
|
What are two other names for Adrenaline?
|
1) Epinephrine
2) "Fight or Flight" Hormone |
|
What does Epinephrine (Amine hormone) do?
|
Raises blood glucose level, increases metabolic activity
· Produced in the adrenal medulla |
|
What are the 2 pancreatic hormones?
|
1) Insulin (protein hormone)
2) Glucagon (protein hormone) |
|
What does Insulin do?
|
Lowers blood sugar in response to high blood glucose levels. Does so by stimulating Glycogen formation (sugar storage)
|
|
What does Glucagon do?
|
Stimulates conversion of Glycogen to Glucose. Raises blood sugar
|
|
What does PTH (peptide hormone) do?
|
Increases concentration of Calcium Ions to assist in process of bone maintenance.
|
|

|
1) Progesterone
2) Estrogen 3) Testosterone |
|
What does Progesterone (Steroid hormone) do?
|
Regulates menstrual cycle and pregnancy
|
|
What does Testosterone (Steroid Hormone) do?
|
Stimulates sex characteristics in men
|
|
What does Estrogen (steroid hormone) do?
|
Stimulates sex characteristics in women.
Induces release of LH. |
|
What are the 2 thyroid hormones?
|
1) Calcitonin
2) Thyroxine |
|
What does Calcitonin (Peptide Hormone) do?
|
Lowers concentration of Calcium Ions. Works against PTH.
|
|
What does Thyroxine (Amine hormone) do?
|
Stimulates metabolic activites
|
|
What is an example of negative feedback in hormone secretion?
|
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.
|
|
What is an example of positive feedback in hormone secretion?
|
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.
|
|
What is negative feedback?
|
Hormone acts to directly or indirectly inhibit further secretion of its own hormone kind.
|
|
What is positive feedback?
|
Hormone acts to directly or indirectly cause increased secretion of itself.
|
|
What does FSH do? (2 func.)
|
· Stimulates activities of gonads.
· In females, induces development of follicle. |
|
What does LH do? (2 func.)
|
· Stimulates ovulation and formation of corpus luteum.
· Stimulates synthesis of estrogen and progesterone. |
|
What does TSH do?
|
· Stimulates synthesis and secretion of thyroid hormones that regulate metabolism
|
|
What do Growth Hormones (protein hormone) do?
|
Stimulate protein synthesis and general growth in body
|
|
What does PRL stand for?
|
Prolactin (protein hormone)
|
|
