- Target Cells
- Exocrine Glands
- Steroid Hormones
- a Secrete substances through ducts (basically tubes). These substances can be water, enzymes, and mucus.
- b Specific cells that hormones travel to, to produce a specific effect.
- c Lipid hormones that are made from cholesterol by the body. They are also fat soluble.
- d A group of sex hormones secreted by the testes.
- e 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.
5 Multiple choice questions
- 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.
- This gland is located near the base of the brain and it secretes melatonin.
- 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.
- A molecule that causes changes inside a cell in response to the binding of a specific substance to a receptor on the outside of a cell. Cyclic AMP is a common second messenger. ATP is converted to make cAMP.
- Ductless organs that secrete hormones either into the bloodstream or into the extra-cellular fluid or liquid around the cell.
5 True/False questions
Adrenal Gland → 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.
Secretin → This hormone is secreted by the pineal gland and probably helps regulate sleep patterns.
Glucagon → A hormone secreted by digestive cells that stimulates other stomach cells to release digestive enzymes such as hydrochloric acid.
Receptors → Released by endocrine cells in the small intestine, a hormone that stimulates the release of various digestive fluids from the pancreas.
Hormones → 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.
