- a Promotes the production of glucose from proteins making usable energy available to cells.
- 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 Secrete substances through ducts (basically tubes). These substances can be water, enzymes, and mucus.
- d The 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.
- e It is caused by insulin deficiency in the body. This condition means that cell are unable to obtain glucose, resulting in abnormally high blood glucose readings.
5 Multiple choice questions
- The endocrine glands and specialized cells as a whole.
- 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.
- A hormone secreted by digestive cells that stimulates other stomach cells to release digestive enzymes such as hydrochloric acid.
- 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.
- 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.
5 True/False questions
Amino Acid-Based Hormones → Many hormones work together in pairs to regulate the level of critical substances. These hormones have opposite effects.
Thyroid Gland → Located near the lower part of the larynx, this endocrine gland secretes the hormones thyroxine and triiodothyronine. Both of these hormones are derived from the same amino acid and are synthesized with iodine atoms. Thyroid-stimulating hormones (TSH) regulates the release of the thyroid hormones. Release of TSH from the anterior pituitary gland is regulated by the hypothalamus. The thyroid gland is important because it promotes human development because it produces calcitonin which stimulates the transfer of calcium ions from the blood to the bone. The thyroid hormones help maintain normal heart rate, blood pressure and body temperature. They also stimulate enzymes that are associated with glucose oxidation, oxygen consumption, generating heat, and increasing cellular metabolic rates. Lastly, they promote carbohydrate usage over fat usage for energy.
Epinephirine & Norepinephrine → 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.
Antagonistic Hormones → Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
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.
