endocrine system Flashcards
cortex (adrenal)
outer portion of adrenal glands
medulla (adrenal)
inner portion of adrenal glands
adrenal glands
paired glands, one located above each kidney; outer portion is adrenal cortex; inner portion is adrenal medulla;
epinephrine and norepinephrine secreted
parathyroid glands
4 small bodies embedded in posterior aspect of lobes of thyroid gland; PTH = parathyroid hormone is the hormone produced by glands, maintains cal levels
thyroid gland
largest endocrine gland; located anteriorly in the neck below larynx; secrets T3 T4 which require iodine for production
hypothalamus
keeps body in homeostasis; located above pit gland in brain; secrets hormones that stimulate or inhibit release of pit gland hormones
hyperkalemia
Excessive potassium in blood
acromegaly
a rare condition where the body produces too much growth hormone, causing body tissues and bones to grow more quickly
adrenalitis
inflammation of adrenal glands
adrenomegaly
enlargement of adrenal glands
endocrinopathy
disease of endocrine system
hypercalcemia
excessive calcium in the blood
hyperglycemia
excessive sugar in the blood
hyperparathyroidism
overactive parathyroid
hyperpituitarism
overactive pituiatry gland
hypocalcemia
not enough calcium in blood
hypokalemia
not enough potassium in blood
hyponatremia
not enough salt in blood
hypopituitarism
underachieve pit gland
