The adrenal glands (also known as suprarenal glands) are endocrine glands that produce a variety of hormones including adrenaline and the steroids aldosterone and cortisol. [1][2] They are found above the kidneys. Each gland has an outer cortex which produces steroid hormones and an inner medulla.

2022年5月13日 · What are adrenal glands? Your adrenal glands, also known as suprarenal glands, are small, triangle-shaped glands that are located on top of each of your two kidneys. They’re a part of your endocrine system and produce certain hormones that help regulate several important bodily functions, including:

Adrenal glands, also known as suprarenal glands, are small, triangular-shaped glands located on top of both kidneys. Adrenal glands produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.

2023年5月1日 · The adrenal gland is made up of the cortex and medulla. The cortex produces steroid hormones including glucocorticoids, mineralocorticoids, and adrenal androgens, and the medulla produces the catecholamines, epinephrine, and norepinephrine.

2025年1月18日 · adrenal gland, either of two small triangular endocrine glands one of which is located above each kidney. In humans each adrenal gland weighs about 5 grams (0.18 ounce) and measures about 30 mm (1.2 inches) wide, 50 mm (2 inches) long, and 10 mm (0.4 inch) thick.

The adrenal glands, located superior to each kidney, consist of two regions: the adrenal cortex and adrenal medulla. The adrenal cortex—the outer layer of the gland—produces mineralocorticoids, glucocorticoids, and androgens.

2024年2月8日 · They are retroperitoneal structures and composed of two major regions: the outer adrenal cortex and the inner adrenal medulla. The main secreting cells of the adrenal medulla are called chromaffin cells, which are neuroendocrine cells that are modified sympathetic ganglia. The chromaffin cells are neural crest cell derivatives.

2024年9月27日 · What is Adrenal Gland? The adrenal glands, commonly referred to as the suprarenal glands, are critical components of the endocrine system, located on the superior aspect of each kidney.

The adrenal medulla is composed of chromaffin cells, which synthesize and secrete catecholamines (mainly epinephrine and lesser amounts of norepinephrine). Chromaffin cells also produce bioactive amines and peptides (eg, histamine, …

The adrenal glands are paired endocrine glands found on top of the kidneys. They are composed of an inner medulla and an outer cortex, which is in turn divided into three zones. The adrenal medulla is the central part of the adrenal gland.
