Adrenal gland
Adrenal gland
A gland responsible for producing hormones such as cortisol and aldosterone, vital for stress response and electrolyte balance.
Adrenal cortex zones
Adrenal cortex zones
Different areas of the adrenal cortex produce distinct steroid hormones.

Study Notes
Adrenal Gland Structure and Function
- The adrenal gland is a composite endocrine gland.
- Different zones within the cortex produce different steroid hormones.
- The hypothalamic-pituitary system regulates cortisol and, to a lesser extent, aldosterone secretion.
- Corticotropin releasing factor (CRF) and adrenocorticotropic hormone (ACTH) control cortisol production.
- Aldosterone production is primarily regulated by the renin-angiotensin system.
Addison's Disease and Adrenal Steroid Use
- Adrenal cortex failure (Addison's disease) necessitates steroid replacement therapy.
- Adrenal steroids are primarily used in medicine for their anti-inflammatory and immunosuppressive properties.
- Therapeutic use requires doses significantly higher than physiological replacement levels.
- High doses can lead to adverse metabolic effects.
