Endocrine system

 Endocrine glands make hormones secreted by which go directly into bloodstream.  Major pituitary glands- pituitary, thyroid, parathyroid, adrenals, Islets of Langerhans- (in the pancreas)

 Growth Hormone (GH)  Adrenocorticotropic hormone (ACTH)  Thyroid-Stimulating Hormone (TSH)  Follicle-Stimulating Hormone (FSH)  Luteinizing Hormone (LH)  Prolactin Hormone (PRL)  Antidiuretic Hormone (ADH)  Oxytocin

 Pituitary- master gland  Thyroid- regulates metabolism  Parathyroid glands- PTH regulates blood Ca  Islets of Langerhans- found throughout pancreas, secrete insulin, glucagon.

 Hormone made in Islets of Langerhans-  Raises blood sugar level, has opposite effect of insulin  Released by pancreas when blood sugar level is too low.  Causes liver to convert stored glycogen into glucose.

 Hormone made in Islets of Langerhans-  Regulates energy and glucose metabolism in the body.  Lowers high blood sugar levels.  Causes cells in liver, muscle, fat tissue to take up glucose from blood.  Stored as glycogen in liver and muscle.

 Cortisol  Epinephrine  Norepinephrine  T4, T3  Aldosterone

 Aden/o =  Adren/o, adrenal/o =  Cortic/o = cortex  Endocrin/o =  Parathyroid/o =  Pituitar/o =

 Thyroid/o, thyr/o =  Acr/o =  Calc/i =  Dips/o =  Kal/i =  Natr/o =  Suffix:  - drome = run, running

 Parathyroidoma  Hypothyroidism  Hyponatremia  Adrenalitis  Adenomegaly

 Acromegaly  Hyperpituitarism  Hypocalcemia  Hypolycemia  Hypokalemia  Adnenosis

 Excessive production of cortisol. May be a result of a pituitary tumor or adrenal gland dysfunction.  Abnormal concentration of ketone bodies resulting from excessive fat metabolism.

 Enlargement of the thyroid gland  Caused by ___ deficiency  Condition brought about by over production of growth hormone

 Condition affects nerves causing muscle spasms. Caused by low ____ blood. Due to a deficiency of ______ hormone.

 Resistance of body cells to the action of insulin. Usually occurs in middle-aged or elderly pts. Diet, exercise, meds, insulin can help.  Beta cells are destroyed, eventually insulin not produced. Occurs in childhood.

Growth hormone regulates the growth of the body.

C.adrenal

The meaning of the medical term tetany is a condition: A.affecting nerves causing muscle spasms as a result of low amounts of calcium B.resulting from a deficiency of the thyroid hormone thyroxine C.caused by excessive thyroid hormones D.brought about by overproduction of growth hormone

A.affecting nerves causing muscle spasms as a result of low amounts of calcium

RAIU abbreviates the medical term meaning: A.nuclear medicine scan that measures thyroid function B.blood test to determine the amount of glucose in the blood C.blood test that measures the amount of thyroid-stimulating hormone in the blood D.a blood study that gives the direct measurement of the amount of thyroxine in the blood

A.nuclear medicine scan that measures thyroid function

 Endocrinopathy  Euglycemia  Polydispsia  Syndrome  Adrenocorticohyperplasia

 Sum total of all the chemical processes that take place in the body.  Chemical substances that are produced and secreted by endocrine glands, carried into bloodstream.  Narrow strip of tissue connecting two large parts in the body

 DM  HbA1C  T4  RAIU  FBS
