Chapter 16

 Regulates body activities through the use of chemical messengers called hormones  Hormones, when released in the bloodstream, influence metabolic activities, growth, and development  Hormones secreted by the endocrine glands (which make up the Endocrine System) go right into the bloodstream and travel throughout the entire body = these are called ductless glands  Exocrine or duct glands – have ducts that carry their secretions from the producing gland to other parts of the body  Major endocrine glands & organs – Pituitary gland, Thymus gland, Ovaries & Testes, Pancreas, Adrenal gland, Thyroid gland (parathyroid)

Aden/o gland Adren/o, adrenal/o.....adrenal glands Cortic/o cortex Endocrin/o endocrine Parathyroid/o......parathyroid glands Pituitar/o pituitary gland Thyroid/o, thyr/o thyroid gland

Acr/o.....extremities, height Calc/i calcium Dips/o thirst Kal/i potassium Natr/o sodium Suffix: -drome run, running

Please breakdown the following terms and define: 1. Hypothyroidism 2. Hyperglycemia 3. Adenectomy

 Adren/o/megaly – enlargement of the adrenal glands  Hypo/natr/emia – deficient sodium in blood  Hyper/thyroid/ism – state of excessive thyroid gland activity  Hypo/glyc/emia – deficient sugar in blood (in diabetics)  Hypo/thyroid/ism – state of deficient thyroid gland activity  Parathyroid/oma – tumor of parathyroid gland

 Gigantism – condition brought about by overproduction of growth hormone by pituitary gland before puberty  Goiter – enlargement of thyroid gland  Diabetes mellitus – chronic disease involving a disorder of CHO metabolism caused by under-activity of islets of Langerhans and high blood sugar

 Aden/ectomy – excision of a gland  Thyroid/o/tomy – incision of the thyroid gland  Fasting blood sugar – blood test performed after patient has been fasting for 8-10 hrs to determine BG levels  Thyroid-stimulating hormone level – test to determine hyperthyroidism
