- Target Cells
- Luteinizing Hormone (LH)
- a 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.
- b These inhibit production and secretion of anterior-pituitary hormones.
- c Specific cells that hormones travel to, to produce a specific effect.
- d Ductless organs that secrete hormones either into the bloodstream or into the extra-cellular fluid or liquid around the cell.
- e 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.

- 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.
- Released by endocrine cells in the small intestine, a hormone that stimulates the release of various digestive fluids from the pancreas.
- 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.
- Substances that are released by cells that act to regulate the activity of other cells in the body.
- 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.
5 True/False questions
Testosterone → An androgen secreted by the testes that regulates male secondary sex characteristics. It also, along with FSH, stimulates sperm production.
Releasing Hormone → Stimulate the anterior pituitary to make and secrete hormones.
Steroid Hormones → Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
Amino Acid-Based Hormones → Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
Positive Feedback → 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.
