5 Written questions

5 Matching questions

  1. Anterior pituitary
  2. Effects of aging on endrocrine system
  3. Thyroid-Stimulating Hormone (THS)
  4. Antidiuretic Hormone
  5. Hormonal regulation soon after a meal
  1. a Blood glucose levels, including amino acids and fatty acids, increase. Taken up into cells.. Parasympathetic stimulation and increasing blood glucose levels cause increased insulin secretion from pancreas. Nutrients move into cells.
  2. b Posterior Pituitary. Also called vasopressin, promotes water retention by kidneys. Secretion rate changes in response to alterations in blood osmolality and blood volume. Lack of ADH secretion is a cause of diabetes insipidus
  3. c Gradual decrease in secretory activity of some glands- GH, Melatonin, Thyroid hormones, Kidneys secrete less renin. Familial tendency to develop Type II diabetes.
  4. d Anterior Pituitary. Also called Thyrotropin. Causes release of thyroid hormones from thyroid gland. Controlled by TRH from hypothalamus and thyroid hormones from the thyroid gland
  5. e called the Adenohypophysis, consists of three areas with indistinct boundaries (pars distalis, pars intermedia, and pars tuberalis)

5 Multiple choice questions

  1. Disorder 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 Pituitary. Cause fat breakdown and release of fatty acids into circulatory system
  3. Posterior Pitutitary. Associated with pregnancy and birth. Promotes uterine contractions during delivery. Causes milk ejection in lactating women by stimulating smooth muscle-like cells associated with the alveoli of mammary glands. Also associated with the contraction of the smooth muscle of the uterus during menses and sexual intercourse. Stretch of the uterus, mechanical stimulation of the cervix, and stimulation of the breast nipples as in nursing stimulates oxytocin secretion. Not much is known about the effects of oxytocin in males
  4. an extension of the nervous system and is called the neurohypophysis, continuous with the brain, secretes neurohormones
  5. Also called the suprarenal glands. Functions as part of sympathetic nervous system. Composed of medulla and cortex (3 layers- zona glomerulosa, fasciculata, and reticularis). Hormones- Medulla secretes epinephrine and norepinephrine. Cortex secretes mineralocorticoids, glucocorticoids, androgens

5 True/False questions

  1. 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

          

  2. Secreted by digestive tractan extension of the nervous system and is called the neurohypophysis, continuous with the brain, secretes neurohormones

          

  3. ThymosinPosterior Pitutitary. Associated with pregnancy and birth. Promotes uterine contractions during delivery. Causes milk ejection in lactating women by stimulating smooth muscle-like cells associated with the alveoli of mammary glands. Also associated with the contraction of the smooth muscle of the uterus during menses and sexual intercourse. Stretch of the uterus, mechanical stimulation of the cervix, and stimulation of the breast nipples as in nursing stimulates oxytocin secretion. Not much is known about the effects of oxytocin in males

          

  4. HypothalamusDecreased 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

          

  5. Diabetes MellitusResults from inadequate secretion of insulin or inability of tissues to respond to insulin. Type I or IDDM (insulin dependent) develops in young people resulting from diminished insulin secretion. Type II or NIDDM (non-insulin dependent) develops in people older than 40-45 and is more common (obesity), results from the inability of tissues to respond to insulin.
