hormone pt1

Question 1

Gonadocorticoids

Answer 1

Made in- Adrenal cortex
Target tissue- Reproductive organs, skin, muscles
Effect- puberty, libido
Too much- Adrenogenital syndrome (masculinization
Too little-Minimal effect in adults (main source is gonads)

Question 2

Aldosterone

Answer 2

Made in: Adrenal cortex

Target tissue: Kidneys

Effect: Increases sodium retention and potassium excretion, raises blood pressure

Too much: Hyperaldosteronism (high BP, low potassium)

Too little: Addison’s disease (low BP, salt craving)

Question 3

Glucocorticoids

Answer 3

(e.g., Cortisol)
Made in: Adrenal cortex

Target tissues: Liver, muscles, immune system

Effect: Increases blood glucose, suppresses immune response

Too much: Cushing’s syndrome

Too little: Addison’s disease

Question 4

Epinephrine

Answer 4

Made in- Adrenal medulla
Target tissues- Heart, lungs, liver, muscles
Effect- “Fight or flight” — increases HR, BP, glucose
Too much- Pheochromocytoma (high BP, anxiety)
Too little-Rarely problematic due to other compensations

Question 5

norepinephrine

Answer 5

Made in- Adrenal medulla
Target tissues- Blood vessels, heart
Effect- alertness, controls BP
Too much- high bp hypertension
Too little- Rare clinical issues

Question 6

ACTH (Adrenocorticotropic Hormone)

Answer 6

Made in: Anterior pituitary

Target tissue: Adrenal cortex

Effect: Stimulates release of cortisol

Too much: Cushing’s disease

Too little: Addison’s disease (indirectly due to low cortisol)
