What does pth do?
Acts agnostically to calcitonin (increases blood [ca])
What is the main blood [ca] regulation technique?
- too much [ca] = more calcitonin and less pth release
- not enough [ca] = less calcitonin and more pth release
What glands are more active when blood [ca] is a) too low and b) too
high?
A) parathyroid
B) thyroid
What are the three layers of the adrenal cortex from least to most
deep?
- zona glomerulosa
- zona fasciculata
- zona reticularis
,The zona glomerulosa produces which hormones?
Mineralcorticoids (aldosterone)
The adrenal medulla produces what hormones?
Epinephrine
What is the function of aldosterone in the body?
Causes kidney tubules to reabsorb more na leading to an increased bp
What is the cascade that occurs when blood [na] is down and or blood
[k] is up?
1) kidneys release renin
2) renin triggers release of angiotensin 1
3) angiotensin 1 triggers release of angiotensin 2
4) angiotensin 2 triggers adrenal cortex to release aldosterone
5) aldosterone causes kidney tubules to increase [na] reuptake
Anp inhibits the release of what hormone?
Aldosterone
,What are the two types of mineralcorticoids?
- glucocorticoid
- gonadocorticoids
What are the purposes of glucocorticoids?
Ensure the brain has sufficient glucose by promoting:
- glucogenisis
- fat mobilization
- protein breakdown
Which age groups are most affected by gonadotropins?
Menopausal women and pre-pubescent
What are the underlying causes of addison's disease?
Too low aldosterone and cortisol
What are the symptoms of addison's disease?
- chronic dehydration
, - hypertension
- bronze skin
What causes the bronzing of the skin for people with addison's disease?
Low cortisol = too much crh = increased melanin production
If a disease is caused by medical interference with normal body
functions, the disease is said to be __________.
Iantrogenic
Cushing's disease is caused by ________.
Too high levels of cortisol
What are the symptoms of cushing's disease?
- high blood glucose levels
- wasting
- moon face
- buffalo hump
- depressed immune function
