Adrenal Cortex vs. Adrenal Medulla: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 29, 2023
The adrenal cortex is the outer part of the adrenal gland that produces steroid hormones; the adrenal medulla is the inner part that produces adrenaline.

Key Differences

The adrenal cortex is the outer layer of the adrenal gland, and it produces a range of steroid hormones including cortisol, aldosterone, and androgens. The adrenal medulla, on the other hand, is the innermost part of the gland, and it produces catecholamines, such as adrenaline and noradrenaline.

While the adrenal cortex is vital for maintaining fluid and electrolyte balance through the production of aldosterone, the adrenal medulla plays a key role in the body’s fight-or-flight response by releasing adrenaline. These two components of the adrenal gland work together to help the body respond to stress.

The hormones produced by the adrenal cortex have effects on nearly every tissue in the body and are vital for life. In contrast, while the hormones produced by the adrenal medulla are important for responding to stress, they are not essential for life. Both the adrenal cortex and adrenal medulla are regulated by different mechanisms and have different functions within the body.

The adrenal cortex is involved in the production of hormones that regulate metabolism, immune system function, and other vital processes. The adrenal medulla, however, functions mainly as a part of the sympathetic nervous system, releasing adrenaline and noradrenaline in response to stress. Both the adrenal cortex and adrenal medulla are essential components of the adrenal gland, playing crucial roles in maintaining homeostasis within the body.
