Study Notes
Adrenal Cortex Zones
- Mineralocorticoids, responsible for regulating salt and water metabolism, are produced in the zona glomerulosa of the adrenal cortex.
Glucocorticoids
- Glucocorticoids, synthesized in the zona fasciculata, play a crucial role in regulating carbohydrate, protein, and fat metabolism.
- The primary function of glucocorticoids is to promote normal intermediary metabolism.
Regulation of Adrenal Cortex
- The hormone ACTH (Adrenocorticotropic Hormone) controls the secretion of the two inner zones of the adrenal cortex.
- Corticosterone serves as a feedback inhibitor of ACTH and CRH secretion.
Zona Reticularis
- The inner zona reticularis of the adrenal cortex synthesizes androgens, a type of steroid hormone.
Glucocorticoids and Stress
- The principal human glucocorticoid is cortisol.
- Glucocorticoids play a primary role in increasing resistance to stress by promoting the breakdown of fat, protein, and carbohydrates to produce energy.
Corticosteroids
- Corticosteroids differ in their activity based on their ability to affect glucocorticoid receptors or mineralocorticoid receptors.
Inflammatory Response
- Glucocorticoids suppress the inflammatory response by reducing the production of pro-inflammatory cytokines.
