ADRB1
ADRB1 (adrenoceptor beta 1) encodes the human beta-1 adrenergic receptor, a 477-amino-acid GPCR on chromosome 10 mediating cardiac sympathetic response and targeted by beta-blockers; Arg389Gly (rs1801253) modifies beta-blocker response.
ADRB3
ADRB3 (BETA3AR), adrenoceptor beta 3, is a human chromosome 8p11.23 gene encoding the beta-3 adrenergic receptor, a Gs/Gi-coupled GPCR regulating lipolysis and thermogenesis in adipose tissue; its Trp64Arg (rs4994) variant is linked to obesity.

Adrenal cortex
Adrenal cortex: outer steroid-secreting region of the adrenal (suprarenal) gland, about 90% of its mass. Three zones: glomerulosa (aldosterone), fasciculata (cortisol), reticularis (DHEA and androgens), regulated by ACTH and angiotensin II.
Adrenal Cortex Function Tests
Adrenal cortex function tests: ACTH (cosyntropin) stimulation test, insulin tolerance, CRH, and metyrapone tests for adrenal insufficiency, plus dexamethasone suppression testing for Cushing's syndrome, with cortisol and ACTH cutoffs.
Adrenal crisis
Adrenal crisis (acute adrenal insufficiency, Addisonian crisis) is a life-threatening cortisol deficiency emergency in adrenal insufficiency, treated with immediate 100 mg hydrocortisone, saline resuscitation, and sick-day steroid dosing.
Adrenal gland
Adrenal gland: paired endocrine glands atop the kidneys; cortex makes cortisol, aldosterone, and androgen precursors, medulla makes epinephrine and norepinephrine. First described by Eustachio in 1564; cortisone work won the 1950 Nobel Prize.
Adrenal insufficiency
Adrenal insufficiency, including Addison's disease (primary AI) and secondary/tertiary AI, is deficient cortisol production; diagnosed by ACTH stimulation testing and treated with lifelong glucocorticoid replacement and emergency hydrocortisone for adrenal crisis.
Adrenal medulla
Adrenal medulla: inner, chromaffin-cell portion of the adrenal gland, neural crest derived, secreting epinephrine and norepinephrine under splanchnic nerve control; distinct from the steroid-producing adrenal cortex, with pheochromocytoma as its main disorder.
Adrenal vein sampling
Adrenal vein sampling is an interventional radiology procedure that draws blood from the adrenal veins to determine which gland causes primary aldosteronism, guiding adrenalectomy; it has been used for over 50 years.
Adrenalectomy
Adrenalectomy is the surgical removal of one or both adrenal glands, performed to cure hormone overproduction or remove suspicious masses, usually by minimally invasive surgery.
Adrenalin Hotel
Adrenalin Hotel (готель «Адреналін») is a 70-room ski hotel at 1,350 m in Dragobrat, Zakarpattia, Ukraine, with restaurant, sauna, salt room, pool, and a 9.2/10 Booking.com rating; distinct from Adrenalin Park Hotel Arkhyz and Adrenalin Attractions.
Adrenalin Park (Egypt)
Adrenalin Park (حديقة الأدرينالين) is a paintball and adventure venue in Sheikh Zayed, 6th of October, Egypt, founded 2010, with three fields (Armageddon, Castle, Village), laser tag at Dandy Mall, and corporate team building via Adrenalin Experience.
Adrenaline
Adrenaline, also called epinephrine, is a catecholamine hormone released by the adrenal glands in response to acute stress, increasing heart rate, breathing rate, blood pressure, and blood sugar.
Adrenaline (album)
Adrenaline is Deftones' 1995 debut album on Madonna's Maverick label, produced by Terry Date in Seattle; a foundational nu metal record with "Bored" and "7 Words" that went platinum via touring.
Adrenalize
Adrenalize: Def Leppard's fifth studio album (March 1992), the first after guitarist Steve Clark's death, produced by Mike Shipley with Mutt Lange as executive producer; debuted at number one in the UK and US. Also the stage name of a hardstyle producer.
Adrenarche
Adrenarche is the childhood rise in adrenal androgen production, mainly DHEA and DHEAS, from the zona reticularis, beginning around age 6-8, independent of puberty, causing pubic hair, and occurring only in humans and some Old World primates.
Adrenergic neuron
Adrenergic neuron: neuron whose primary neurotransmitter is epinephrine (adrenaline); noradrenergic neurons use norepinephrine. Includes postganglionic sympathetic fibers and brainstem C1/C2 and A1/A2/A6 cell groups with α2 autoreceptor feedback.
Adrenergic receptor
Adrenergic receptor (adrenoceptor): G protein-coupled receptor for adrenaline and noradrenaline, divided into alpha and beta families with nine subtypes; targets of beta-blockers, asthma bronchodilators, and decongestants.
Adreno
Adreno, also known as Qualcomm Adreno, is a series of graphics processing units designed by Qualcomm and integrated into Snapdragon chips for smartphones, tablets, XR headsets, and laptops.
Adrenochrome
Adrenochrome (CAS 54-06-8, C9H9NO3) is the deep violet oxidation product of epinephrine, studied since 1937; its stable derivative carbazochrome is a hemostatic drug, and the QAnon child-harvesting conspiracy about it is debunked.
Adrenocortical carcinoma
Adrenocortical carcinoma (ACC), a rare aggressive cancer of the adrenal cortex, usually hormone-secreting; incidence about 0.5–2 per million yearly; treated by complete resection, mitotane, EDP-M chemotherapy.
Adrenocortical carcinoma with pure aldosterone hypersecretion
Adrenocortical carcinoma with pure aldosterone hypersecretion (pure APAC, ORPHA:231625) is a very rare, surgically correctable primary aldosteronism caused by an aldosterone-secreting adrenal malignancy, marked by renin suppression, hypertension, hypokalemia, and tumors usually over 4 cm.
Adrenocorticotropic hormone
Adrenocorticotropic hormone (ACTH, corticotropin) is a 39-amino acid anterior pituitary peptide, cleaved from POMC, that drives cortisol production via the MC2R receptor in the HPA axis; disorders include Cushing syndrome and adrenal insufficiency.
Adrenocorticotropic hormone deficiency
Adrenocorticotropic hormone (ACTH) deficiency, ICD-11 5A61.1, also called secondary adrenocortical insufficiency: low pituitary ACTH or hypothalamic CRH causing functional hypocortisolism, congenital (TBX19, POMC, PCSK1) or acquired.
Adrenodoxin reductase
Adrenodoxin reductase (FDXR, EC 1.18.1.6) is a monomeric FAD flavoprotein on the inner mitochondrial membrane that transfers electrons from NADPH via adrenodoxin to mitochondrial cytochrome P450 enzymes, enabling steroid hormone biosynthesis; FDXR mutations cause mitochondrial neuropathy.
Adrenoleukodystrophy
X-linked adrenoleukodystrophy (X-ALD, Siemerling-Creutzfeldt disease) is an inherited peroxisomal disorder caused by ABCD1 variants, causing VLCFA buildup, cerebral demyelination, adrenomyeloneuropathy, and adrenal insufficiency, treated by transplant or gene therapy.
