The adrenal cortex is the outer region and also the largest part of the adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. It is also a secondary site of androgen synthesis. [2]
The cortex of the adrenal gland is derived from mesoderm, whereas the medulla is derived from the neural crest, which is of ectodermal origin. [12] The adrenal glands in a newborn baby are much larger as a proportion of the body size than in an adult. [38] For example, at age three months the glands are four times the size of the kidneys.
Cortex means "the outer layer"—a reference to the adrenal cortex, the part of the adrenal gland where cortisol is produced. [110] While the adrenal cortex in humans also produces aldosterone in the zona glomerulosa and some sex hormones in the zona reticularis, cortisol is its main secretion in humans and several other species. [108]
In humans and other animals, the adrenocortical hormones are hormones produced by the adrenal cortex, the outer region of the adrenal gland.These polycyclic steroid hormones have a variety of roles that are crucial for the body's response to stress (for example, the fight-or-flight response), and they also regulate other functions in the body.
Conversely, chronically elevated ACTH levels occur in primary adrenal insufficiency (e.g. Addison's disease) when adrenal gland production of cortisol is chronically deficient. In Cushing's disease, a pituitary tumor leads to excessive production of ACTH, which stimulates the adrenal cortex to produce high levels of cortisol.
Steroid-producing adrenal tumours and hyperplasia of the zona fasciculata result in excess cortisol production and are the cause for adrenal Cushing's syndrome. [1] The genetic disorder McCune–Albright syndrome can also present as Cushing's syndrome in affected patients. Adrenal gland (zona fasciculata layer).
The zona reticularis (sometimes, reticulate zone) is the innermost layer of the adrenal cortex, lying deep to the zona fasciculata and superficial to the adrenal medulla. The cells are arranged cords that project in different directions giving a net-like appearance (L. reticulum - net). [1]
H & E staining of the adrenal cortex. The zona glomerulosa is the outermost layer, below the renal capsule (near the pointer) In response to increased potassium levels, renin or decreased blood flow to the kidneys, cells of the zona glomerulosa produce and secrete the mineralocorticoid aldosterone into the blood as part of the renin ...
