Chapter 8: The Adrenal Glands Flashcards
benign solid mass located within the adrenal glands
adrenal adenoma
hormone secreted by the anterior pituitary gland, which controls the release of hormones by the adrenal glands
adrenocorticotropic hormone
a syndrome caused by a functioning tumor within the adrenal cortex that produces excess amounts of aldosterone; patients will have hypertension, excessive thirst, excessive urination, and low levels of potassium in the blood
Conn syndrome
a syndrome that results from a pituitary or adrenal tumor that causes overproduction of cortisol by the adrenal glands; patients may present with obesity, thinning arms and legs, hypertension, hyperglycemia, and severe fatigue
Cushing syndrome
glands that release their hormones directly into the bloodstream
endocrine glands
high levels of sodium in the blood
hypernatremia
low levels of potassium in the blood
hypokalemia
malignant tumor that can occur within the adrenal gland and anywhere within the sympathetic nervous system
neuroblastoma
benign, solid adrenal tumor associated with uncontrollable hypertension
pheochromocytoma
3 zones of the cortex (outer part) of the adrenal gland
zona glomerulosa
zona fasciculata
zona reticularis
hormone produced by the cortex of the adrenal gland that is responsible for regulating blood pressure by controlling the amounts of sodium and water in the body
aldosterone
3 hormones produced by the cortex of the adrenal gland
aldosterone
androgens
cortisol
2 hormones produced by the medulla (inner part) of the adrenal glands
epinephrine (adrenaline, main one)
norepinephrine
the adrenal glands may also be referred to as:
suprarenal glands
3 arteries that supply the adrenal glands
suprarenal branches of the inferior phrenic arteries
suprarenal branches of the aorta
suprarenal branches of the renal arteries
the right suprarenal vein drains into the ______
IVC
the left suprarenal vein drains into the ______
left renal vein
the normal adrenal glands are often easily visualized in the fetus and pediatric patients as a __________ structure anterior, medial, and superior to the upper pole of each kidney
hypoechoic
