- Follicle-Stimulating Hormone (FSH)
- Releasing Hormone
- Islets of Langerhans
- Amino Acid-Based Hormones
- a 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.
- b 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.
- c A hormone secreted by digestive cells that stimulates other stomach cells to release digestive enzymes such as hydrochloric acid.
- d Stimulate the anterior pituitary to make and secrete hormones.
- 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
- 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.
- 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.
- An androgen secreted by the testes that regulates male secondary sex characteristics. It also, along with FSH, stimulates sperm production.
- Ductless organs that secrete hormones either into the bloodstream or into the extra-cellular fluid or liquid around the cell.
- 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.
5 True/False questions
Androgens → A group of neuropeptides that regulate emotions, influence pain, and affect reproduction.
Secretin → 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 → Substances that are released by cells that act to regulate the activity of other cells in the body.
Parathyroid Glands → 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.
Insulin → 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.
