Unit 11 - Endocrine System Key Terms Flashcards
endocrine
body system that works with the nervous system and includes the pituitary gland, hypothalamus, thyroid gland, parathyroid glands, adrenal glands, pancreatic islets, and gonads.
hormone
the chemical secretion from an endocrine gland, a hormone changes cell functions and alters body activities.
acromegaly
Excessive amounts of the growth hormone from the pituitary gland are secreted during adulthood. It causes enlargement of the bone structures, especially the hands and face.
exophthalmos
An abnormal protrusion of the eyes, it is a symptom of excessive activity of the thyroid gland.
goiter
A nonconstructed term. An abnormal swelling or enlargement of the thyroid gland caused by a tumor, lack of iodine in the diet, or an infection of the gland.
ketosis
A high level of ketone bodies in the blood and urine. It is the result of starvation, low-carb diets (where muscle and fat is being burned for fuel instead of carbohydrates), and of some forms of diabetes.
polydipsia
An abnormal state of excessive thirst, it sometimes accompanies disorders of the pituitary gland or pancreas.
adenosis
general term for any disease of a gland
cretinism
May result when the thyroid gland does not produce normal levels of growth hormones at birth. It results in reduced mental development and physical growth.
Diabetes Insipidus
Results from the under-secretion of ADH… antidiuretic hormone. Symptoms include excessive thirst and excessive urination.
Diabetes Mellitus
The pancreas does not produce enough insulin to metabolize carbohydrates, resulting in high blood sugar levels. Left unmanaged, it may result in kidney, nerve, or eye damage or even death.
Hyperadrenalism
The adrenal cortex produces too much of the hormone cortisol causing Cushing Syndrome. It is characterized by obesity, hyperglycemia, a round face, and muscle weakness.
Hypercalcemia
The parathyroid glands produce too much parathyroid hormone (PTH). This causes the bones to release calcium into the bloodstream, and softening of the bones can result.
Hypoglycemia
This is the opposite of Type 2 diabetes mellitus. There is too much insulin production and blood sugar levels are too low.
Hyperthyroidism
When the thyroid gland produces too much hormone, it may result in exophthalmos (bulging eyes), goiter, rapid heart rate, and weight loss. One chronic form of this is Graves Disease.
