5 Matching questions

  1. Hypothalamus
  2. Short-term and prolonged Exercise
  3. Diabetes Mellitus
  4. Abnormalities in the secretion of growth hormone
  5. Thyroxine and triiodothyronine
  1. a Cause Dwarfism, Giantism in juveniles, and Acromegaly in adults
  2. b Results 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.
  3. c Sympathetic stimulation increases epinephrine and glucagone secretion and inhibits insulin secretion. Muscle, liver, and adipose tissue help maintain blood glucose levels.
  4. d Made from the amino acid, tyrosine. Require iodine for their synthesis. Are transported in the blood by thyroxine-binding globulin, are involved in the regulation of metabolism
  5. e Regulates secretory activity of pituitary gland through neurohormones and action potentials. KNOW HORMONES

5 Multiple choice questions

  1. Hormone like substance known to stimulate T lymphocyte production
  2. 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
  3. Also called hypophyis, secretes 9 major hormones
  4. Anterior Pituitary. Both hormones regulate production of gametes and reproductive hormones. Testosterone in males. Estrogen and progesterone in females. GnRH from hypothalamus stimulates their secretion
  5. Increased metabolic rate, Weight loss, increased appetite, Warm flushed skin, Weak muscles that exhibit tremors, Exophthalmos, Hyperactivity, insomnia, Soft smooth hair and skin, Increased iodide uptake, Almost always develops goiter

5 True/False questions

  1. Within 1-2 hours after mealDecreasing blood glucose levels. Sympathetic stimulation causes decreased insulin secretion, increase glucagon secretion, increase in GH, cortisol, and epinephrine secretion.

          

  2. GlucagonPancreas. Secreted by Alpha cells. Target tissue is liver. Causes breakdown of glycogen and fats for glucose energy. Increases glucose synthesis in liver. (to increase blood glucose levels!)

          

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

          

  4. Adrenal Cortex HormonesMineralocorticoids, Glucocorticoids, and Androgens

          

  5. Thyroid glandOne of largest endocrine glands. Composed to two lobes connected by isthmus. Highly vascular. Composed of follicles. Parafollicular cells secrete calcitonin which reduces calcium concentration in body fluids when levels elevated
