Ch 9 Endocrine System Diseases/Disorders/Treatments

• Enlargement of bone structure most prominent in the hands and face, results in disfigurement and is caused by hypersecretion of growth hormone from the pituitary gland after puberty

The use of radioactive iodine to treat a disease of the thyroid gland, such as a thyroid tumor

• Abnormally low blood sugar levels

Abnormal development of the adrenal cortex; results in its excessive size and hypersecretion of its hormones

• Diagnostic procedure that records an image of the thyroid gland following the oral administration of a labeled substance, usually iodine; used to detect thyroid tumors

Diagnostic procedure that measure thyroid function, in which radioactive iodine uptake into the thyroid gland is measured

• Caused by a deficiency of parathyroid hormone; the low calcium levels in the blood lead to excitation of nerves and muscle spasms

Diagnostic test to determine blood sugar levels following a 12-hour fast; extreme variation in blood sugar is an indication of diabetes mellitus

• Tumor of the parathyroid gland

• Caused by hyposecretion of growth hormone by the pituitary gland at an early age, it slows growth and causes a short but proportional stature—can be treated with growth hormone therapy
