Adrenal Cortex[edit | edit source]
Overview[edit | edit source]
The adrenal cortex is the outer region of the adrenal glands, which are small but crucial endocrine organs located on top of each kidney. This cortex plays a vital role in hormone production, specifically androgens and corticosteroids, essential for various bodily functions.
Anatomy and Location[edit | edit source]
- The adrenal cortex surrounds the inner adrenal medulla.
- Each adrenal gland is divided into three distinct zones: the zona glomerulosa, zona fasciculata, and zona reticularis.
Hormone Production[edit | edit source]
Androgens[edit | edit source]
- Androgens, such as testosterone, are male sex hormones but are also present in females.
- They are responsible for the development of male characteristics and reproductive activity.
Corticosteroids[edit | edit source]
- The adrenal cortex produces two main types of corticosteroids: glucocorticoids and mineralocorticoids.
- Glucocorticoids, like cortisol, regulate the body's stress response, metabolism, and immune response.
- Mineralocorticoids, such as aldosterone, control blood pressure and electrolyte balance.
Functions[edit | edit source]
- Regulating metabolism and the immune system.
- Maintaining blood pressure and cardiovascular function.
- Managing the body's response to stress.
Disorders of the Adrenal Cortex[edit | edit source]
- Conditions like Addison's Disease and Cushing's Syndrome result from the dysfunction of the adrenal cortex.
- Addison's Disease is characterized by insufficient hormone production, whereas Cushing's Syndrome involves excessive hormone production.
Diagnostic Tests[edit | edit source]
- Blood tests to measure levels of adrenal hormones.
- Imaging tests like CT scans or MRIs to assess the structure of the adrenal glands.
Treatment and Management[edit | edit source]
- Hormone replacement therapy for conditions like Addison's Disease.
- Surgical intervention in cases of adrenal tumors or hyperplasia.
