functional anatomy and approach to endocrine disorders

Question 1

What are the different parts of the adrenal gland

Answer 1

adrenal cortex and adrenal medulla

Question 2

What are the 3 zones in the adrenal cortex

Answer 2

Zona glomerulosa
Zona fasciculata
Zona reticularis

Question 3

What does the zona glomerulosa produce

Answer 3

Mineralocorticoids - aldoseterone

Question 4

What does the zona fasciculata produce

Answer 4

Glucocorticoids - cortisol

Question 5

Zona reticularis

Answer 5

Sex steroids e.g testosterone

Question 6

What does the renal medulla produce

Answer 6

Norepinephrine and epinephrine

Question 7

Describe how cortisol is released

Answer 7

CRH - corticotropic releasing hormone from the hypothalamus goes to the anterior pituitary and stimulates release of ACTH - adenocorticotropic hormone - this goes to the adrenal gland and stimulates the zona fasciculata to release glucogorticoids such as cortisol

Question 8

What are steroid hormones produced from

Answer 8

Cholesterol

Question 9

What is aldosterone

Answer 9

Mineralocorticoid - hormone that regulates the blood pressure by managing potassium and calcium levels in the blood

Question 10

What causes the different zones to produce different hormones even though all steroid hormones are produced from cholesterol

Answer 10

The enzymes in the zones are different which results in different end products
