Term
eu-
Definition
Good, normal Example: Euthyroid: A state in which the thyroid gland functions normally, producing the right levels of thyroid hormones necessary for metabolism and growth.
Term
hyper-
Definition
Above, excessive Example: Hyperthyroidism: A condition in which the thyroid gland produces excessive thyroid hormones, leading to symptoms such as rapid heartbeat, weight loss, and nervousness.
Term
hypo-
Definition
Below, under, deficient Example: Hypoglycemia: A condition characterized by abnormally low blood sugar levels, often causing symptoms such as dizziness, shakiness, and confusion.
Term
oxy-
Definition
 Rapid, sharp, acid Example: Oxytocin: A hormone released by the pituitary gland that stimulates uterine contractions during childbirth and the release of milk during breastfeeding.
Term
pan-
Definition
All, total Example: Panhypopituitarism: A condition in which the pituitary gland fails to produce or secretes all of its hormones, leading to a wide range of endocrine dysfunctions.
Term
para-
Definition
Around, beside, beyond, abnormal Example: Parathyroid: Small glands located beside the thyroid gland, responsible for regulating calcium levels in the blood and bone metabolism.
Term
poly-
Definition
Many or much Example: Polyuria: Excessive urination, a common symptom of diabetes mellitus due to high blood sugar levels affecting kidney function.
Term
syn-
Definition
Joined, together Example: Synergistic hormones: Hormones that work together to amplify their effects, such as insulin and growth hormone in promoting cell growth.
Term
tetr-
Definition
Four Example: Tetralogy of Fallot: A condition involving four congenital heart defects that may indirectly affect endocrine function due to oxygenation issues.
Term
tri-
Definition
Three Example: Triiodothyronine (T3): A thyroid hormone that contains three iodine atoms and plays a critical role in regulating metabolism and energy levels.
Term
-drome
Definition
Run, running together Example: Syndrome: A group of symptoms or signs that occur together, such as Cushing’s syndrome, which results from excessive cortisol production by the adrenal glands.
Term
-ectomy
Definition
Excision, cut out Example: Thyroidectomy: Surgical removal of the thyroid gland, often performed to treat conditions such as hyperthyroidism, thyroid cancer, or goiters.
Term
-emia
Definition
Condition of the blood Example: Hyperglycemia: High levels of glucose in the blood, commonly associated with diabetes mellitus and requiring careful monitoring and management.
Term
-ism
Definition
State of Example: Hypothyroidism: A state of underactive thyroid function, resulting in reduced production of thyroid hormones and symptoms like fatigue, weight gain, and cold intolerance.
Term
-itis
Definition
Inflammation Example: Thyroiditis: Inflammation of the thyroid gland, which may result from autoimmune conditions like Hashimoto's thyroiditis or infections.
Term
-logist
Definition
Specialist who studies and treats Example: Endocrinologist: A medical specialist who studies and treats disorders of the endocrine system, such as diabetes, thyroid diseases, and hormonal imbalances.
Term
-logy
Definition
Study of Example: Endocrinology: The study of the endocrine system, including the glands, hormones, and their related diseases.
Term
-megaly
Definition
Enlarged, enlargement Example: Acromegaly: Abnormal enlargement of extremities caused by excessive growth hormone secretion from the pituitary gland in adulthood.
Term
-oid
Definition
 Resembling Example: Adrenoid: Resembling the adrenal glands in shape or function, possibly used in anatomical studies or to describe tissue with adrenal-like characteristics.
Term
-oma
Definition
 Tumor Example: Insulinoma: A tumor of the pancreas that produces excessive amounts of insulin, often leading to episodes of hypoglycemia.
Term
-pathy
Definition
Disease Example: Adenopathy: A disease or enlargement of glandular tissue, such as in swollen lymph nodes or glandular dysfunction in the endocrine system.
Term
-plasia
Definition
 Condition of, formation, development, growth Example: Hyperplasia: Excessive growth or formation of cells within an endocrine gland, such as adrenal hyperplasia, which can affect hormone production.
Term
-tomy
Definition
Incision, cut into Example: Adrenalotomy: A surgical incision into the adrenal gland, often performed to remove a tumor or investigate gland abnormalities.
Term
aden/o
Definition
Gland Example Adenoma: A benign tumor of an endocrine gland, such as a pituitary adenoma, which can affect hormone production and cause symptoms like vision problems or hormonal imbalances.
Term
adren/o, adrenal/o:
Definition
Adrenal glands Example Adrenalectomy: Surgical removal of one or both adrenal glands, often performed to treat adrenal tumors or excessive hormone secretion.
Term
calc/i
Definition
Calcium Example Hypercalcemia: An elevated level of calcium in the blood, often caused by overactivity of the parathyroid glands (hyperparathyroidism).
Term
cortic/o
Definition
Cortex, outer layer of a body organ Example Corticosteroids: Hormones produced by the adrenal cortex, such as cortisol, which play roles in stress response, immune regulation, and metabolism.
Term
dips/o
Definition
Thirst Example Polydipsia: Excessive thirst, commonly associated with diabetes mellitus or diabetes insipidus due to hormonal imbalances affecting water regulation.
Term
endocrin/o
Definition
Endocrine Example Endocrinopathy: A disease or disorder affecting the endocrine system, including the glands and hormones that regulate bodily functions.
Term
glyc/o
Definition
Sugar Example Hyperglycemia: Elevated blood sugar levels, a hallmark of diabetes mellitus caused by insufficient insulin production or action.
Term
home/o
Definition
Sameness Example Homeostasis: The maintenance of a stable internal environment in the body, such as balanced hormone levels to regulate metabolism and growth.
Term
kal/i
Definition
Potassium Example Hypokalemia: A condition characterized by low potassium levels in the blood, which can result from adrenal dysfunction such as hyperaldosteronism.
Term
myx/o
Definition
Mucus Example Myxedema: Severe hypothyroidism characterized by swelling and deposits of mucus-like substances in the skin, often affecting the face and extremities.
Term
natr/o
Definition
Sodium Example Hyponatremia: A condition characterized by low sodium levels in the blood, which can result from hormonal imbalances such as adrenal insufficiency.
Term
parathyroid/o
Definition
Parathyroid gland Example Parathyroidectomy: Surgical removal of one or more parathyroid glands, often performed to treat hyperparathyroidism and manage calcium imbalances.
Term
