5 Matching questions

  1. Neurosecretory Cells
  2. Androgens
  3. Endocrine Glands
  4. Estrogen & Progesterone
  5. Gastrin
  1. a Ductless organs that secrete hormones either into the bloodstream or into the extra-cellular fluid or liquid around the cell.
  2. b A hormone secreted by digestive cells that stimulates other stomach cells to release digestive enzymes such as hydrochloric acid.
  3. c A group of sex hormones secreted by the testes.
  4. d 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. e These sex hormones are stimulated to be produced by LH and FSH in females. In preparation for a possible pregnancy, these sex hormones cause the monthly release of an egg by an ovary and buildup of the uterine lining. Estrogen also regulates female secondary sex characteristics.

5 Multiple choice questions

  1. A group of neuropeptides that inhibits pain messages traveling towards the brain.
  2. Substances that are released by cells that act to regulate the activity of other cells in the body.
  3. It 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. 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.
  5. It is located beneath the sternum and between the lungs. It plays a role in the development of the immune system. This gland secretes thymosin.

5 True/False questions

  1. PancreasIt mostly contains exocrine cells, but specialized cells in the pancreas call the islets of Langerhans, function as an endocrine gland.

          

  2. GlucagonAn amino acid-based hormone that stimulates the release of glucose into the bloodstream by liver cells.

          

  3. TestosteroneAn androgen secreted by the testes that regulates male secondary sex characteristics. It also, along with FSH, stimulates sperm production.

          

  4. CortisolSubstances that are released by cells that act to regulate the activity of other cells in the body.

          

  5. Target CellsSpecific cells that hormones travel to, to produce a specific effect.
