1
Q
Adrenal gland
A
- located on top of each kidney
- 5cm long, 1-cm thick, 3 cm wide
- has an inner core, medulla, and a thick outer covering (the cortex), with distinct endocrine functions
2
Q
What does the Adrenal Cortex secrete?
A
- glucocorticoids (cortisol)
- mineralocorticoids (aldosterone)
- sex hormones (androgens and estrogens)
3
Q
Cortisol
A
primary glucocorticoid
- actions include carbohydrate, fat, and protein metabolism
- suppression of the immune response
- control of the body’s stress response
4
Q
Aldosterone
A
primary mineralocorticoid
-action is to promote sodium and water reabsorption and potassium excretion in the kidneys
5
Q
Overview of Adrenal Cortex
A
> Hormone: Glucocorticoids (Cortisol)
- Targets: Liver
- Action: promotes gluconeogenesis (increasing blood glucose)
> Hormone: Glucocorticoids (Cortisol)
- Targets: Cells in the Body
- Action:
- decreases glucose use
- promotes protein catabolism
- promotes fat synthesis
> Hormone: Glucocorticoids (Cortisol)
- Targets: Bone Marrow
- Action: suppresses inflammatory response
> Hormone: Mineralocorticoids (aldosterone)
- Targets: Distal tubules and collecting ducts in the kidneys
- Action: promotes sodium reabsorption and potassium excretion by the kidneys
6
Q
Overview of The Adrenal Medulla
A
> Hormone: Catecholamines (epinephrine and norepinephrine)
- Targets: cells of the body
- Action: mimics actions of the sympathetic nervous system
