Question

Cortisol function in target tissues can be INHIBITED via all of the following ways EXCEPT:

1. Preventing release from binding to transcortin (plasma protein)
2. Increasing intake of cholesterol (via LDL receptor) into adrenal cortex cells
3. Inhibiting ACTH secretion
4. Preventing binding to glucocorticoid receptor
5. Inhibiting CRH production

ACTH has a major role in stimulating the production of _____ in the adrenal cortex:

1. Epinephrine
2. Aldosterone
3. Cortisol
4. Adrenal androgens
5. All of the above
6. A and B
7. C and D

The adrenal cortex is responsible for secreting all of the following hormones EXCEPT for:

1. Aldosterone
2. CRH
3. Androstenedione
4. DHEA
5. Cortisol
6. ACTH
7. DHEA-S

Answer 1

1. b - increasing intake of cholestrol into adrenal cortex cells.

2. c - cartisol

ACTH means Adrenocorticptropic Harmone which stimulates the adrenal cortex. It stimulates the secretion of steroid harmone cartisol. It has capacity to have little control over aldosterone secretion. ACTH is produced in pituitary gland.

3. CRH - Carticotropin

It is secreted by paraventricular nucleus of the hypothalamus in response to stress.
