What is the outer portion of the adrenal gland called?

The outer portion of the adrenal gland is known as the adrenal cortex. This region plays a critical role in producing a variety of hormones, including cortisol, aldosterone, and androgens. These hormones are involved in regulating metabolism, blood pressure, immune response, and stress management, making the adrenal cortex essential for maintaining several bodily functions.

In contrast, the adrenal medulla, which is the inner part of the adrenal gland, is responsible for producing catecholamines like adrenaline and norepinephrine, which are involved in the body's fight-or-flight response. The pancreas and thyroid are entirely separate organs with different functions; the pancreas is involved in digestion and blood sugar regulation, while the thyroid regulates metabolism through hormone release. Understanding the specific roles and locations of these glandular structures is crucial for grasping how the endocrine system operates as a whole.
