CCNN Endocrine Sys

The Humam Body in Health or Illness Chap 14

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
