5 Matching questions

  1. Follicle-Stimulating Hormone (FSH)
  2. Secretin
  3. Puberty
  4. Neuropeptides
  5. Hypoglycemia
  1. a Released by endocrine cells in the small intestine, a hormone that stimulates the release of various digestive fluids from the pancreas.
  2. b Hormones secreted by the nervous system. Unlike neurotransmitters, they tend to affect many cells near the nerve cells that release them.
  3. c 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. d 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.
  5. e 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.

5 Multiple choice questions

  1. Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
  2. 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.
  3. 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.
  4. A hormone secreted by digestive cells that stimulates other stomach cells to release digestive enzymes such as hydrochloric acid.
  5. Substances that are released by cells that act to regulate the activity of other cells in the body.

5 True/False questions

  1. Adrenal GlandThis gland is located near the base of the brain and it secretes melatonin.


  2. Neurosecretory CellsSpecific cells that hormones travel to, to produce a specific effect.


  3. HypothalamusThe area of the brain that coordinates many activities of the nervous and endocrine systems. It receives information from other brain regions and then responds to these signals as well as to blood concentrations of circulating hormones.


  4. Antagonistic HormonesMany hormones work together in pairs to regulate the level of critical substances. These hormones have opposite effects.


  5. Estrogen & ProgesteroneThese 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.
