13.3 Hormonal Regulation Of The Stress Response

Question 1

Adrenal gland

Answer 1

Rests ontop of kidney, divides into adrenal cortex and adrenal medulla

Question 2

Short term stress effects

Answer 2

Adrenal medulla produced epinephrine and norepinephrine. Influences blood glucose

Question 3

Short term stress target tissue

Answer 3

Travels to liver to increase conversion of glycogen into glucose

Question 4

Short term stress Hypersecretion and hyposecretion

Answer 4

Hyper: high blood pressure, high blood glucose.
Hypo: low blood pressure, low blood glucose and fatigue

Question 5

What hormones does the Adrenal cortex produce

Answer 5

Glucocorticoids (ex. Cortisol): controls blood sugar
And mineralcorticoids (ex. Aldosterone): regulates blood pressure

Question 6

Cortisol source and target tissue

Answer 6

Hypothalamus releases CRH and goes to the pituitary gland. Pit. Releases ACTH which goes to the adrenal cortex. Adrenal cortex releases cortisol.

Question 7

Cortisol effects

Answer 7

Cortisol breaksdoen protein into amino acids which the liver converts into glucose.

Question 8

Aldosterone source tissue and target

Answer 8

Released from adrenal cortex and travels to the kidneys

Question 9

Aldosterone effects

Answer 9

Increases Blood pressure by controlling Na+ concentration. High Na+ reabsorption, water follows by osmosis. High blood volume and blood pressure

Question 10

Adrenal gland dysfunction hypo and hyper

Answer 10

Hypo: low cortisol, aldosterone and Blood pressure, dehydration and salt cravings
Hyper: high cortisol and aldosterone, hypertension (excess aldosterone), diabetes mellitus
