Endocrine System 2 Flashcards
antagonistic
acting in opposition; mutually opposing
electrolyte
mineral salt that carries an electrical charge in solution
glucagon
hormone produced by pancreatic alpha cells that stimulates the liver to change stored glycogen to glucose
glucose
simple sugar that is the end product of carbohydrate digestion
insulin
hormone produced by pancreatic beta cells that allows body cells to use glucose for energy or store it in the liver as glycogen
sympathomimetic
agent that mimics the effects of the sympathetic nervous system
adren/o adrenal/o
adrenal glands
calc/o
calcium
crin/o
secrete
gluc/o glyc/o glycos/o
sugar, sweetness
home/o
same, alike
kal/i
potassium (an electrolyte)
pancreat/o
pancreas
parathyroid/o
parathyroid glands
thym/o
thymus gland
thyr/o thyroid/o
thyroid gland
toxic/o
poison
-crine
secrete
-dipsia
thrist
acromegaly
rare hormonal disorder in adulthood, usually cause by a GH-secreting pituitary tumor that promotes the soft tissue and bones of the face, hands, and feet to grow larger than normal
diuresis
increased formation and secretion of urine
glycosuria
abnormal amount of glucose in the urine
Graves disease
multisystem autoimmune disorder characterized by pronounced hyperthyroidism usually associated with enlarged thyroid gland and exophthalmos
hirsutism
excessive distribution of body hair, especially in women
hypercalcemia
condition in which the calcium level in the blood is higher than normal
hyperkalemia
condition in which the potassium level in the blood is higher than normal
hypervolemia
abnormal increase in the volume of blood plasma in the body
hyponatremia
lower than normal level of sodium in the blood
insulinoma
tumor of the islets of Langerhans of the pancreas
obesity
excessive accumulation of fat that exceeds the body’s skeletal and physical standards, usually an increase of 20 percent or more above ideal body weight
morbid obesity
BMI 40 or greater
panhypopituitarism
total pituitary impairment that brings about a progressive and general loss of hormone activity
pheochromocytoma
small chromaffin cell tumor, usually located in the adrenal medulla, causing elevated heart rate and blood
thyroid storm
crisis of uncontrolled hyperthyroidism caused by the release into the blood stream of an increased amount of thyroid hormone
virilism
masculinization or development of male secondary sex characteristics in a woman
exophthalmometry
measures the degree of foward displacedment of the eyeball as seen in Graves disease
parathyroidectomy
excision of one or more of the parathyroid glands, usually to control hyperparathyroidism
transsphenoidal hypophysectomy
endoscopic procedure to sugically remove a pituitary tumor through an incision in the sphenoid sinus without disturbing brain tissue
thymectomy
excision of the thymus gland
thyroidectomy
excision of the entire thyroid gland, a part of it, or a single lobe
fasting blood sugar
test that measures glucose levels in a blood sample following a fast of a least 8 hrs
glucose tolerance test (GTT)
screening test in which a dose of glucose is administered and blood samples are take afterward at regular intervals to determine how quickly glucose is cleared from the blood
insulin tolerance test (ITT)
diagnostic test in which insulin is injected into the vein to assess pituitary function, adrenal function, and to dtermine insulin sensitivity
thyroid function test (TFT)
test that detects an increase or decrease in thyroid function
total calcium test
test that measures calcium to detect bone and parathyroid disorders
radioactive iodine uptake (RAIU)
administration of a radioactive iodine (RAI) in pill or liquid form is used as a tracer to test how quickly the thyroid gland takes up iodine from the blood
thyroid scan
images of the thyroid gland are obtained after oral or intravenous administration of a small dose of radioactive iodine
antidiuretics
vasopressin (Pitessin, Pressyn) - reduce or control excretion of urine
antithyroids
methimazole (Tapazole) or strong iodine solution - treat hyperthyroidism
corticosteroids
cortisone or hydrocortisone - replace hormones lost in adrenal insufficiency
growth hormone replacements
somatropin
insulins
regular insulin, NPH insulin, insulin aspart
oral antidiabetics
glipizide or metformin - treat type 2 diabetes
thyroid supplements
levothyroxine or liothyronine - replace or supplement thyroid hormones
ACTH
adrenocorticotropic stimulating hormone
ADH
antidiuretic hormone
DI
diabetes insipidus
DKA
diabetic ketoacidosis
DM
diabetes mellitus
FBS
fasting blood sugar
FSH
follicle-stimulating hormone
GH
growth hormone
HRT
hormone replacement therapy
K
potassium
LH
luteinizing hormone
NPH
neutral protamine Hagedorn (insulin)
PRL
prolactin
PGH
pituitary growth hormone
PTH
parathyroid hormone
T3
triiodothyronine
T4
thyroxine
