5 Matching questions

  1. Short-term and prolonged Exercise
  2. Endocrine system functions
  3. Thyroid hormones
  4. Insulin
  5. Glucocorticoids
  1. a Sympathetic stimulation increases epinephrine and glucagone secretion and inhibits insulin secretion. Muscle, liver, and adipose tissue help maintain blood glucose levels.
  2. b Metabolism and tissue maturation, Ion regulation, Water balance, Immune system regulation, Heart rate and blood pressure regulation, Control of blood glucose and other nutrients, Control of reproductive functions and secondary sex characteristics, Uterine contractions and milk release
  3. c Include Triiodothryronine or T3 and Tetraiodothyronine or T4 or thyroxine. Transported in blood. Bind with intracellular receptor molecules and initiate new protein synthesis. Increase rate of glucose, fat, protein metabolism in many tissues thus increasing body temperature. Normal growth of many tissues dependent on thyroid hormones. Calcitonin from parafollicular cells reduces blood calcium levels
  4. d Pancreas. Secreted by Beta cells. Target tissues: liver, adipose tissue, muscle, and satiety center of hypothalamus. Increases uptake of glucose and amino acids by cells. (in order to decrease blood glucose levels!)
  5. e Zona fasciculata, Cortisol is major hormone that increases fat and protein breakdown, increases glucose synthesis, anti-inflammatory response (cortosone shot!)

5 Multiple choice questions

  1. Hormone like substance known to stimulate T lymphocyte production
  2. Decreased metabolic rate, Weight gain, reduced appetite, Dry and cold skin, Weak, flabby skeletal muscles, sluggish, Myxedema, Apathetic, somnolent, Coarse hair, rough dry skin, Decreased iodide uptake, Possible goiter, Cretinism
  3. Epinephrine- (increases blood glucose levels, fat breakdown in adipose tissue releasing fatty acids into the blood) and norepinephrine. Both increase heart rate and force of contraction and cause blood vessels to constrict. Prepare individual for physical activity. Short half-life.
  4. Stomach- Gastrin, Histamine. Duodenum- Secretin, Cholecystokinin
  5. Disorders of the adrenal medulla that are tumors. Result of exvessive production of epinephrine and roepinephrine. Symptoms are high blood pressure, sweating, nervousness, pallor, and tachycardia (rapid heart rate).

5 True/False questions

  1. Effects of aging on endrocrine systemDisorder characterized by hypersecretion of cortisol and androgens and possibly by excess aldosterone production. Causes increased blood glucose levels, muscle wasting, and accumulation of adipose tissue in the face and trunk of the body.


  2. Anterior pituitarycalled the Adenohypophysis, consists of three areas with indistinct boundaries (pars distalis, pars intermedia, and pars tuberalis)


  3. Growth Hormone (GH)Anterior Pituitary. Stimulates uptake of amino acids and conversion into proteins. Stimulates breakdown of fats and glycogen. Promotes bone and cartilage growth. Increased secretion in response to increase in amino acids, low blood glucose, or stress. Regulated by GHRH and GHIH or somatostatin


  4. PancreasExocrine and endocrine. Endocrine part consists of pancreatic islets each of which is composed of alpha, beta, and delta cells. Secretes Glucagon, Insulin, and Somatostatin.


  5. OvariesMales, from Gonads, Testosterone- regulates production of sperm cells and function of male reproductive organs and secondary sex characteristics. Inhibin- inhibits FSH secretion
