- Adrenal Gland
- Follicle-Stimulating Hormone (FSH)
- Luteinizing Hormone (LH)
- a The ovaries in females, and the testes in males. These are gamete-producing organs that also produce a group of steroid sex hormones. Sex hormones regulate body changes that begin at puberty.
- b A group of sex hormones secreted by the testes.
- c One of these is located over each kidney and each has an inner core, the medulla and the outer layer, the cortex. The medulla and cortex function as separate endocrine glands. Secretion of hormones in the medulla is controlled by the nervous system while hormones in the anterior pituitary regulate secretion of hormones in the cortex. The cortex responds specifically to adrenocorticotropic hormone (ACTH), which is secreted by the anterior pituitary gland.
- 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. In males it stimulates the testes to secrete a group of sex hormones called androgens. An example of an androgen is testosterone.
- e 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 Multiple choice questions
- An amino acid-based hormone that stimulates the release of glucose into the bloodstream by liver cells.
- This hormone is secreted by the pineal gland and probably helps regulate sleep patterns.
- Secrete substances through ducts (basically tubes). These substances can be water, enzymes, and mucus.
- This is an amino acid-based hormone that is secreted by the thymus gland. The hormone stimulates the maturation of T cells, which help defend the body from pathogens.
- 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
Negative Feedback → One way to maintain homeostasis inside an organism or cell, is a negative feedback loop. In this process the final step in a series of events inhibits the initial signal in the series.
Releasing Hormone → Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
Hyperthyroidism → 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.
Hypothalamus → 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.
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.
