Chapter 13 (Vocabulary) Flashcards
A rare chronic disease characterized by abnormal enlargement of the extremities (hand and feet) caused by the excessive secretion of growth hormone after puberty.
acromegaly
An abnormal growth of the entire body that is caused by excessive secretion of growth hormone before puberty.
gigantism
The excess secretion of growth hormone that causes acromegaly and gigantism.
hyperpituitarism
Formerly known as dwarfism, is sometimes caused by deficient secretion of growth hormone.
short stature
There are two type of these slow-growing benign tumors of the pituitary gland. Functioning pituitary tumors - often produce hormones in large and unregulated amounts. Non-functioning pituitary tumors do not produce any significant amounts of these hormones.
pituitary adenoma, aka pituitary tumor
A condition in which an excess of prolactin causes the breasts to produce milk spontaneously.
galactorrhea
A benign tumor of the pituitary gland that causes it to produce too much prolactin, which can cause infertility in women and erectile dysfunction in men, and can impair vision.
prolactinoma
Is caused by an insufficient production of the antidiuretic hormone ADH or by the inability of the kidneys to respond appropriately to this hormone. *see notes pg. 3/19
diabetes insipidus
Caused by the overproduction of the anti-diuretic hormone ADH. This is often as a result of cancer or its treatment. High amts. of ADH keep the kidneys from excreting water, resulting in bloating and water retention that can dilute the blood, causing electrolyte imbalances, particularly hyponatremia.
syndrome of inappropriate antidiuretic hormone (SIADH)
Is a tumor of the pineal gland that can disrupt the production of melatonin. This tumor can also cause insomnia by disrupting the circadian cycle.
pinealoma
The most common cancer of the endocrine system. This cancer affects more women than men and usually occurs btw the ages 25-65 years.
thyroid carcinoma
Aka chronic lymphocytic thyroiditis, is an autoimmune disease in which the body’s own antibodies attack and destroy the cells of the thyroid gland. This inflammation often leads to hypothyroidism.
Hashimoto’s disease [Memory aid > “o” in Hashimoto’s and hypo]
Aka underactive thyroid, is caused by a deficiency of thyroid secretion. Symptoms include fatigue, depression, sensitivity to cold, and a decreased metabolic rate.
hypothyroidism
Is a congenital form of hypothyroidism. If treatment is not started soon after birth, this causes arrested physical and mental development.
cretinism
Aka adult hypothyroidism, is causes by an extreme deficiency of thyroid secretion. Symptoms include swelling, particularly around the eyes and cheeks, fatigue, and a subnormal temperature.
myxedema
Are lumps in the thyroid that can grow large enough to cause goiter (see Graves disease). Most nodules are benign; however some are malignant or produce too much thyroxine.
thyroid nodules
Aka thyrotoxic crisis, is a relatively rare, life-threatening condition caused by exaggerated hyperthyroidism. Symptoms include fever, chest pain, palpitations, shortness of breath, tremors, increased sweating, disorientation, and fatigue.
thyroid storm
Aka thyrotoxicosis, is the overproduction of thyroid hormones, which causes an imbalance of the metabolism. This causes symptoms including an increased metabolic rate, sweating, nervousness, and weight loss.
hyperthyroidism [Most common cause is Grave’s disease.]
A disorder of unknown cause in which the immune system attacks the thyroid gland and stimulates it to make excessive amounts of thyroid hormone (autoimmune disorder). This results in hyperthyroidism and can also cause a goiter, exophthalmos, or both.
Grave’s disease (hyperthyroidism) [Memory aid > “e” in Grave’s and in hyper]
Aka thyromegaly, is an abnormal nonmalignant enlargement of the thyroid gland. This enlargement produces a swelling in the front of the neck. Usually occurs when the thyroid gland is not able produce enough thyroid hormone to meet the body’s need, either due to Grave’s disease, other medical conditions, or an iodine deficiency.
