Ch. 13 Endocrine/Ch. 15 Urinary Study Guide/Abbreviations Flashcards
Endocrine gland is a ductless gland that secretes . . .
hormones directly into the bloodstream.
The pituitary gland is a pea-sized gland, behind and slightly above . . .
the nose and throat
The anterior pituitary gland secretes 7 hormones. What are they?
GH - growth hormone ACTH - adrenocorticotropic hormone TSH - thyroid-stimulating hormone LTH - lactogenic hormone FSH - follicle-stimulating hormone LH - luteinizing hormone MSH - melanocyte-stimulating hormone
The posterior pituitary gland secretes 2 hormones. What are they?
ADH - antidiuretic hormone
OT - oxytocin
What does the pineal gland do?
secretes melatonin
induces sleep
Where is the thyroid gland located?
in front of the neck, below larynx
The thyroid gland secretes what 3 hormones?
T3 (triiodothyronine) - growth and development
T4 (thyroxine) - metabolism
calcitonin - regulates calcium levels in blood
What is the parathyroid gland?
4 rounded bodies on the dorsum of the thyroid
What does the parathyroid gland secrete?
parathyroid hormone
regulates levels of calcium in the blood
Where is the thymus?
mediastinum beneath the sternum
the thymus shrinks with age
What 2 hormones does the thymus secrete?
thymosin and thymopoietin
both stimulate production of T cells
Where are the adrenal glands located?
2 glands, 1 per kidney, atop each kidney
What do the adrenal glands secrete?
corticosteroids and hormones
What are the 2 hormones secreted by adrenals?
epinephrine (adrenaline)
norepinephrine (noradrenaline) returns body to normal
Where is the pancreas located?
LUQ - behind the stomach
The pancreas contains a group of cells called . . .
islets of Langerhans
What does the islets of Langerhans do?
produces hormones: glucagon and insulin
Define acromegaly
hyperexcretion of the human growth hormone (HGH)
usually due to a pituitary gland tumor
treatment is surgery/radiation
Diabetes insipidus is . . .
deficiency of secretion of ADH (antidiuretic hormone)
excretion of large amounts of urine and sodium
patients have excessive thirst - drink excess water
Diabetes mellitus is . . .
common form of diabetes lack of insulin production by the pancreas sugar present in the urine Type I Type II
Hyperplasia of the thyroid gland is:
goiter
possibly from lack of iodine
Graves’ disease is . . .
hyperthyroidism
it causes exophthalmos (bulging eyeballs)
treated with antithyroid medication, radioiodine, and surgery
Define diabetic retinopathy . . .
capillaries of the retina have localized areas of bulging (microaneurysms), hemorrhages, leakage, and scarring eventually resulting in loss of vision.
Cushing’s syndrome:
adrenal glands produce excessive corticosteroids
symptoms are weight gain, fatigue, and moon-like facies
disease of a gland
adenopathy
steroid hormone that increases male characteristics
androgen
suppresses urine production
antidiuretic
islets of Langerhans fail to produce enough insulin
diabetes mellitus
normal thyroid
euthyroid
secretes substance through ducts
exocrine gland
outward protrusion of eyeballs
exophthalmos
Glucagon is . . .
hormone secreted by islets of Langerhans
stimulates liver to convert glycogen into glucose
excessive body hair in a male distribution pattern
hirsutism
elevated blood calcium levels
hypercalcemia
low blood potassium levels
hypokalemia
