The hormones of the adrenal medulla are released when the sympathetic nervous system is stimulated, which occurs when you are stressed by physical or emotional reasons.

Unlike the adrenal cortex, the adrenal medulla does not make hormones which are essential or needed to live. However, their impact is usually overshadowed by the greater amounts of hormones (such as estrogen and testosterone) released by the ovaries and testes.

Sex Steroids: are released in very small amounts of male and female sex hormones.

Aldosterone: is the mineralocorticoid which maintains the right balance of salt and water while helping control blood pressure.

Corticosterone: This hormone works with hydrocortisone to regulate immune response and suppress inflammatory reactions.

It also helps regulate blood pressure and cardiovascular function.

Hydrocortisone: Commonly known as cortisol, it regulates how the body converts fats, proteins, and carbohydrates to energy.

Hormones released by the adrenal cortex include: Mineralocorticoids are mediated by different signals triggered by the kidney. These hormones, in turn, alert the adrenal glands to produce glucocorticoid hormones. When the hypothalamus produces corticotrophin-releasing hormone (CRH), it stimulates the pituitary gland to release adrenocorticotrophic hormone (ACTH). The release of glucocorticoids is triggered by the hypothalamus and pituitary gland. The adrenal cortex hormones, glucocorticoids and mineralocorticoids, are essential hormones that maintain adequate blood flow which maintains oxygen and nutrients to all cells.

The adrenal medulla - the inner part of the gland produces other hormones, such as adrenaline and noradrenaline (which helps your body react to stress).

The adrenal cortex – the outer part of the gland produces glucocorticoid hormones that are vital to life, such as cortisol (which helps regulate metabolism and helps your body respond to stress) and mineralocorticoids, such as aldosterone (which helps control blood pressure by adjusting water and salt levels in the bloodstream).

In fact, they release hormones that are essential for you to live.Īn adrenal gland is made up of two distinct parts:

But the adrenal glands contribute to your health even at times when your body isn’t under extreme stress. The adrenal glands are arguably best known for secreting the stress hormones, which rapidly prepare your body to spring into action (flight, fright, fight). When you think of adrenal glands, stress might come to mind. There are normally two adrenal glands, triangular-shaped organs that measure about 1.5 by 3 inches, which are located on top of each kidney.
