adrenal

adrenal  

1 pertaining to or produced by the adrenal glands.2 the adrenal gland itself.
adrenal cortex

adrenal cortex  

The outermost layer of the adrenal gland, which releases corticosteroid hormones such as cortisol (hydrocortisone) into the bloodstream in response to stress (1). See also adrenocorticotrophic ...
adrenal corticosteroid

adrenal corticosteroid  

A family of steroid hormones formed in the adrenal cortex. There are more than 30 of these hormones, and all are synthesized from cholesterol by cortical cells that have been stimulated by the ...
adrenal medulla

adrenal medulla  

The inner part of the adrenal gland, containing chromaffin cells that release adrenalin (epinephrine) and noradrenalin (norepinephrine) into the bloodstream in response to fear or stress.
adrenal medullary hormone

adrenal medullary hormone  

Any catecholamine hormone elaborated and secreted by the adrenal medulla. See adrenal gland.
adrenal virilism

adrenal virilism  

Condition found in females with hyperactive adrenal glands producing male hormones at a concentration high enough to give rise to male characteristics (see masculinization). Compare testicular ...
adrenalectomy

adrenalectomy  

Reference type:
Overview Page
n. the surgical removal of an adrenal gland, usually performed because of neoplastic disease.
adrenaline

adrenaline  

Reference type:
Overview Page
A hormone secreted by the medulla of the adrenal gland, and by adrenergic neurons of the sympathetic nervous system. Adrenaline induces the ‘fight or flight’ responses: increased heart function, an ...
adrenocortical

adrenocortical  

Of, pertaining to, or derived from the cortex of the adrenal gland, e.g. adrenocortical hormone. See adrenal androgen, corticosteroid.
adrenocorticotrophic hormone

adrenocorticotrophic hormone  

Reference type:
Overview Page
(ACTH)A hormone produced by the pituitary gland which stimulates the adrenal glands to produce cortisone. Large amounts are produced in response to stress.
adrenomedullary

adrenomedullary  

Of, pertaining to, or derived from the medulla of the adrenal gland.
aldosterone

aldosterone  

A hormone produced by the adrenal glands that controls excretion of sodium by the kidneys and thereby maintains the balance of salt and water in the body fluids.
androgen

androgen  

Reference type:
Overview Page
A general term for any male sex hormone. Androgen insensitivity syndrome, caused by mutation in the androgen receptor gene, is also referred to as testicular feminization, and genetic males are ...
chromaffin

chromaffin  

A group of cells in the adrenal medulla (see adrenal glands) that synthesizes noradrenaline. Chromaffin tissue also contains the enzyme that converts noradrenaline into adrenaline.
cortex

cortex  

Reference type:
Overview Page
The outer layer of any organ or part, such as the cerebrum, the cerebellum, or adrenal gland. Often used as a shorthand for the cerebral cortex. cortical adj. [From Latin cortex bark or outer layer]
corticosteroid

corticosteroid  

The steroid hormones secreted by the adrenal cortex that regulate carbohydrate metabolism (glucocorticoids such as cortisol and cortisone) and salt/water balance (minerocorticoids, e.g. aldosterone). ...
corticosterone

corticosterone  

A corticosteroid hormone, produced by the adrenal cortex in the adrenal gland, that in many animal species regulates the metabolic release of energy, immune reactions, and response to stress.
cortisol

cortisol  

Reference type:
Overview Page
n. a steroid hormone: the major glucocorticoid synthesized and released by the human adrenal cortex (see corticosteroid). It is important for normal carbohydrate metabolism and for the normal ...
cortisone

cortisone  

A corticosteroid hormone secreted by the adrenal cortex that suppresses inflammation and promotes carbohydrate formation. See also DHEA. [From corti(co)s(ter)one]
Cushing's syndrome

Cushing's syndrome  

Reference type:
Overview Page
An endocrine disorder (hyperadrenocorticism, hypercorticism) in which there is overproduction of cortisol in response to excessive secretion of adrenocorticotropic hormone (ACTH), usually from a ...
