5 Matching questions

  1. Epinephirine & Norepinephrine
  2. Endocrine Glands
  3. Hypothyroidism
  4. Neurosecretory Cells
  5. Enkephalins
  1. a These amino acid-based hormones produced in the adrenal medulla are also known as adrenaline and noradrenaline. These hormones work together to orchestrate the nervous system's reaction to stress and its "fight-or-flight" reaction response to danger. When a person is stressed the medulla secretes both hormones into the bloodstream. They increase heart rate, blood pressure, blood glucose level, and blood flow to the heart and lungs. They also stimulate enlargement of the bronchial tubes and dilation of the pupils.
  2. b Ductless organs that secrete hormones either into the bloodstream or into the extra-cellular fluid or liquid around the cell.
  3. c When there is a deficiency in thyroid hormones. Symptoms of this include: growth retardation, lethargy, weight gain, and low heart rate and body temperature. It can also cause cretinism, a form of mental retardation.
  4. d A group of neuropeptides that inhibits pain messages traveling towards the brain.
  5. e Nerve cells that secrete hormones. The axons of these cells in the hypothalamus extend into the posterior lobe of the pituitary. Oxytocin and ADH are transported through these axons into the posterior pituitary where they are stored for eventual release into the bloodstream.

5 Multiple choice questions

  1. Excessive insulin causes this, a disorder that causes glucose to be stored rather than used and properly delivered to body cells. This leads to lowered blood glucose concentrations and subsequent release of glucagon and epinephrine. Symptoms include lethargy, dizziness, nervousness, overactivity, and in extreme cases, unconsciousness and death.
  2. A hormone secreted by digestive cells that stimulates other stomach cells to release digestive enzymes such as hydrochloric acid.
  3. The adolescent stage during which the sex organs mature and secondary sex characteristics, such as facial hair appear. In males, during this stage, sperm production begins, the voice deepens, the chest broadens, and hair begins to grow on the body and face. In females, the menstrual cycle begins, the breasts grow, and the hips wide.
  4. An amino acid-based hormone that stimulates the release of glucose into the bloodstream by liver cells.
  5. This is an amino acid-based hormone that is secreted by the thymus gland. The hormone stimulates the maturation of T cells, which help defend the body from pathogens.

5 True/False questions

  1. GonadsPromotes the production of glucose from proteins making usable energy available to cells.

          

  2. Follicle-Stimulating Hormone (FSH)A hormone secreted by the anterior pituitary stimulates secretion of sex hormones from the gonads. It stimulates the secretion of estrogen and progesterone in females.

          

  3. Pituitary GlandIt is suspended from the hypothalamus by a short stalk. The hypothalamus produces hormones that are stored in this gland or that regulate this gland's activity.

          

  4. Exocrine GlandsSecrete substances through ducts (basically tubes). These substances can be water, enzymes, and mucus.

          

  5. HyperthyroidismAbnormal thyroid overactivity can be detrimental to the body's metabolism. Overproduction of the thyroid hormones has some symptoms, such as: overactivity, weight loss, and high blood pressure, and heart rate, and body temperature. It can be treated with medication or by surgically removing part of the thyroid gland.
