5 Matching questions

  1. Pineal Gland
  2. Cortisol
  3. Releasing Hormone
  4. Endocrine Glands
  5. Positive Feedback
  1. a This gland is located near the base of the brain and it secretes melatonin.
  2. b Stimulate the anterior pituitary to make and secrete hormones.
  3. c Another way to maintain homeostasis is a positive feedback loop. In this process, release of an initial hormone stimulates release or production of other hormones or substances which stimulate further release of the initial hormone.
  4. d Promotes the production of glucose from proteins making usable energy available to cells.
  5. e Ductless organs that secrete hormones either into the bloodstream or into the extra-cellular fluid or liquid around the cell.

5 Multiple choice questions

  1. 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.
  2. Abnormal 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.
  3. An amino acid-based hormone that stimulates the release of glucose into the bloodstream by liver cells.
  4. Hormones made of amino acids. They can be a single modified amino acido or a protein made up of 3-200 amino acids. They are usually water soluble.
  5. Specialized cells in the pancreas that act as an endocrine gland. They secrete two amino acid-based hormones that regulate the level of sugar in the blood. The hormones are insulin and glucagon.

5 True/False questions

  1. 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.


  2. Endocrine SystemDuctless organs that secrete hormones either into the bloodstream or into the extra-cellular fluid or liquid around the cell.


  3. Neurosecretory CellsNerve 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.


  4. NeuropeptidesA group of neuropeptides that regulate emotions, influence pain, and affect reproduction.


  5. InsulinA hormone secreted by digestive cells that stimulates other stomach cells to release digestive enzymes such as hydrochloric acid.
