The zona fasciculata, the middle zone, comprises 70 of.

They can increase your heart rate, blood pressure, breathing, strength, and alertness. The zona glomerulosa, the outer zone, is responsible for the secretion of mineralocorticoid hormones. Catecholamines (released by the medulla)Ĭatecholamines (epinephrine and norepinephrine) influence how your body responds to stress or fear.It also makes precursors that can be converted to sex steroids such as androgen, estrogen. Mineralocorticoids: the most important of which is aldosterone. Your DHEA level usually goes down after you turn 30. Adrenal gland secretes steroid hormones such as cortisol and aldosterone. The adrenal cortex produces three hormones, from three different layers: 1. Your body uses DHEA to make male sex hormones (androgens) and female sex hormones (estrogens). If you have an adrenal tumor, it may affect the production of these hormones:Ĭortisol affects your metabolism and helps you recover from physical stress and infection.Īldosterone regulates your sodium and potassium levels, which affect blood pressure and the balance of fluids and electrolytes (water and salt) in your body. Your adrenal glands produce four common hormones. Adrenal glands, also known as suprarenal glands, are small, triangular-shaped glands located on top of both kidneys. The medulla makes hormones that affect how your body responds to stress. The cortex releases hormones that affect your metabolism (the way your body converts what you eat and drink into energy), blood pressure, and physical characteristics, like body shape and where and how much hair grows on your body. The deepest region of the adrenal cortex is the zona reticularis, which produces small amounts of a class of steroid sex hormones called androgens. These two glands, located above the kidneys, are part of your endocrine system, which produces hormones that regulate different bodily functions.Įach adrenal gland has a cortex (an outer layer) and a medulla (an inner region). Adrenal tumors form in the adrenal glands.
