- Endocrine Glands
- Digestive Cells
- Release-Inhibiting Hormone
- a These inhibit production and secretion of anterior-pituitary hormones.
- b 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.
- c 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.
- d A group of sex hormones secreted by the testes.
- 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
- Many hormones work together in pairs to regulate the level of critical substances. These hormones have opposite effects.
- 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.
- 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.
- Hormones secreted by the nervous system. Unlike neurotransmitters, they tend to affect many cells near the nerve cells that release them.
- 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 True/False questions
Diabetes Mellitus → 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.
Parathyroid Glands → There are four of these glands on the back of the thyroid gland and they secrete parathyroid hormone. This stimulates the transfer of calcium ions from the bones to the blood. It has the opposite effect of calcitonin. A proper balance of calcium ions is necessary for cell division, muscle contraction, blood clotting, and neural signaling.
Endorphins → A group of neuropeptides that inhibits pain messages traveling towards the brain.
Receptors → Released by endocrine cells in the small intestine, a hormone that stimulates the release of various digestive fluids from the pancreas.
Testosterone → An androgen secreted by the testes that regulates male secondary sex characteristics. It also, along with FSH, stimulates sperm production.
