What is the outer region of the adrenal glands called?

The outer region of the adrenal glands is known as the adrenal cortex. This area plays a vital role in producing essential hormones such as cortisol, aldosterone, and adrenal androgens. Cortisol is important for metabolism and stress response, aldosterone regulates blood pressure and electrolyte balance, while adrenal androgens contribute to the development of secondary sexual characteristics.

The adrenal medulla, which is the inner part of the adrenal glands, produces catecholamines like adrenaline and norepinephrine, which are involved in the body's fight-or-flight response. The adrenal capsule is a thin layer of connective tissue that surrounds the adrenal glands but does not constitute the functional part of the gland itself. The term adrenal glandular tissue is vague and does not specify whether it refers to the cortex or medulla. Thus, the adrenal cortex is clearly distinguished as the outer region responsible for critical hormonal functions in the body.
