Adrenal Cortex

The adrenal cortex is the outer layer of the adrenal gland, which is located on top of each kidney. It plays a crucial role in producing hormones that are essential for the body's functioning, including cortisol, aldosterone, and androgens.

Functions of the Adrenal Cortex

1. Cortisol: This hormone helps regulate metabolism, immune response, and the body's response to stress. It also plays a role in controlling blood sugar levels.
2. Aldosterone: Aldosterone helps regulate blood pressure and electrolyte balance in the body, particularly by influencing the reabsorption of sodium and water in the kidneys.
3. Androgens: These are male sex hormones, such as testosterone, which are present in both males and females and play a role in the development and maintenance of secondary sexual characteristics.

Study Guide for Adrenal Cortex

1. Describe the structure of the adrenal gland, including its different layers.
2. Explain the functions of the hormones produced by the adrenal cortex, including cortisol, aldosterone, and androgens.
3. Discuss the role of cortisol in the body's stress response and its effects on metabolism and immune function.
4. Examine the importance of aldosterone in regulating blood pressure and electrolyte balance.
5. Compare and contrast the functions of androgens in males and females, including their role in the development of secondary sexual characteristics.
6. Discuss the diseases or disorders associated with the adrenal cortex, such as Cushing's syndrome, Addison's disease, and congenital adrenal hyperplasia.

Understanding the functions and significance of the adrenal cortex is crucial for comprehending the body's endocrine system and its role in maintaining homeostasis and overall health.
