- Steroid Hormones
- a Specific cells that hormones travel to, to produce a specific effect.
- b 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.
- c An amino acid-based hormone that regulates the level of sugar in the blood. It does this by stimulating body cells, especially muscles, to store glucose or use it for energy. It is secreted by the pancreas.
- d Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
- e Many hormones work together in pairs to regulate the level of critical substances. These hormones have opposite effects.
5 Multiple choice questions
- Modified fatty acids that are secreted by most cells. They accumulate in areas where tissues are disturbed or injured. Some reduce blood pressure, and others raise blood pressure. Some cause smooth muscles to contract while still others cause smooth muscles to relax. Some even cause fever. Aspirin and acetaminophen reduce fever and decrease pain by inhibiting prostaglandin synthesis.
- Endocrine cells within the walls of some digestive organs also secrete a variety of hormones that control digestive processes. Some examples of these hormones include gastrin and secretin.
- 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.
- Stimulate the anterior pituitary to make and secrete hormones.
- This hormone is secreted by the pineal gland and probably helps regulate sleep patterns.
5 True/False questions
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. In males it stimulates the testes to secrete a group of sex hormones called androgens. An example of an androgen is testosterone.
Receptors → Released by endocrine cells in the small intestine, a hormone that stimulates the release of various digestive fluids from the pancreas.
Hypothalamus → 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.
Estrogen & Progesterone → 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.
Glucagon → An amino acid-based hormone that stimulates the release of glucose into the bloodstream by liver cells.
