The Humam Body in Health or Illness Chap 14
| Question | Answer |
|---|---|
| Contains the islets of Langerhans | Pancreas |
| Secretes Cortisol, Aldosterone, and Testosterone | Adrenal Medulla |
| Its hormonal secretion is controlled by ACTH | Adrenal Cortex |
| Secretes iodine-containing hormones | Thyroid Gland |
| Secretes Releasing Hormones | Hypothalmus |
| Secretes ACTH, TSH, prolactin, growth hormone, and the gonadotropins | Anterior Pituitary Gland |
| Also called the adenoohypophysis | Anterior Pituitary Gland |
| Secretes both insulin and glucagon | Pancreas |
| Part of the fight-or-flight system; secretes catecholamines | Adrenal Medulla |
| The neurohypophysis; secretes ADH and oxytocin | Posterior Pituitary Gland |
| Stimulates osteoclastic activity to increase blood calcium | Parathyroid Hormone |
| Regulates Metabolic Rate | T3 and T4 |
| The only hormone that lowers blood glucose | Insulin |
| Stimulates osteoclastic activity causing bone resorption | Parathyroid Hormome |
| Stimulates the breast to produce milk; also called lactogenic hormone | Prolactin |
| The hormonal component of the fight-or-flight response | Epinephrine |
| The neurohypophyseal hormone that controls water balance | ADH |
| Stimulates the adrenal cortex to secrete steroids | ACTH |
| Also called somatotropic hormone | Growth Hormone |
| The mineralocorticoid that is called the salt-retaining hormone | Aldosteron |
| Not true of the hypothalmas | Connected to the neurohypophysis by the portal capillaries |
| The posterior pituitary gland | Releases ADH and oxytocin |
| ACTH, TSH, and gonadotropins are | Secreted by the adenohypophysis |
| Cortisol | Is secreted by the adrenal cortex in response to ACTH |
| The adrenal medulla | Secretes catecholamines |
| Aldosteron | Is a mineralocorticoid secreted by the adrenal gland |
| The pancreas | Secretes both insulin and glucagon |
| The function of insulin | Lower blood glucose |
| T3 and T4 | Regulate basal metabolic rate (BMR) |
| Suppressesthe Sectretion of ACTH | Elevated plasma cortisol |
| Growth hormone, cortisol and epinephrine | Raise blood glucose |
| Prolactin | Does not cause milk let-down reflex |
| T3 and T4 | Contain iodine |
| Epinephrine and norepinephrine | Participates in the fight-or-flight response Are Catecholamines Are secreted by the adrenal medulla |
| Concerned with the "sugar, salt, and sex | CAT - cortisol, aldosterone, testosterone, and testosterone |
| A deficiency of dietary iodine | Impairs the synthesis of T3 and T4 |
| Hepatic Gloconeogenesis | Not a function of insulin |
| T3, T4, and Calcitonin | Are thyroid glands |
| Estrogen and progesterone are | Adenhypophyseal hormones |
| A deficiency of ADH is most likely to | Induce polyuria |
| Osteoclastic activity | Elevates plasma calcium. |
| Hyperglycemia | Is due to excess insulin |
| Catecholamines and Steroids | Are secreted by the adrenal gland |
| Persistent long-term stimulation of the thyroid gland by TSH is most likely to | Cause a goiter |
| Cushing's Syndrome | Is due to adrenal insuffiency |
| Polyuria, polydipsia, and polyphagia are | Caused by long-term deficiency of insulin (diabetes mellitus) |
| Cretinism, myexedema, and Grave's disease are | Thyroid disorders |
| Complete this sequence: releasing hormone -- ACTH -- | Cortisol |
| Aldosterone | Expand blood volume |
| Abrupt, sudden withdrawal of prednisone (cortisol) is likely to cause | Acute adrenal insuffiency |
| Cushing's Syndrome is less likely to caused by | Pharmacologic doses of exogenous steroid (prednisone) |
| Glucocorticoids have an unfavorable impact on | Protein metabolism thereby reducing muscle mass, weakening bones, and causing a thinning of the skin. |
| Glucocorticoids can suppress osteoblastic activity, stimulate osteoclastic activty, decrease the intestinal absorption of calcium, and enhance the renal excretion of calcium. For this reason the prolonged use of Glucocorticoids causes | Osteoporosis and vertebral compression fractures |
| Virilization is most likely to be observed in this condition | Aldosterone deficiency |
| Hepatic conversion of protein-breakdown products into glucose | Gluconeogenesis |
| Insulin is released primarily in response to | Increased blood sugar |
| This develops with an insulin deficit | Gluconeogensis |
