Adrenal gland anatomy Flashcards
1
Q
Embryo:
cortex and medulla derived from
A
Cortex: mesoderm (GFR)
Medulla: neural crest (EPI, NE)
2
Q
Zona glomerulosa
A
Afferent: renin-angiotensin
Efferent: aldo
3
Q
Zona fasciculata
A
Afferent: ACTH, hypothalamic CRH
Efferent: cortisol, sex hormone
4
Q
Zona reticularis
A
Afferent: ACTH, hypothalamic CRH
Efferent: sex hormone (androgens)
5
Q
Medulla
A
Afferent: preganglionic sympathetic fibers
Efferent: catecholamines (EPI, NE)
6
Q
Pheo vs. neuroblastoma
A
Both derived from adrenal medulla
Pheo: adults, secrete catecholamines
Neuroblastoma: kids, dopamine (HVA)
7
Q
Adrenal drainage
A
Left adrenal: left adrenal vein => left renal vein => IVC
Right adrenal: right adrenal vein => IVC
Same as gonadal vein
