Understandings:
- Endocrine glands secrete hormones directly into the bloodstream.
- Steroid hormones bind to receptor proteins in the cytoplasm of the target cell to form a receptor–hormone complex.
- The receptor–hormone complex promotes the transcription of specific genes.
- Peptide hormones bind to receptors in the plasma membrane of the target cell.
- Binding of hormones to membrane receptors activates a cascade mediated by a second messenger inside the cell.
- The hypothalamus controls hormone secretion by the anterior and posterior lobes of the pituitary gland.
- Hormones secreted by the pituitary control growth, developmental changes, reproduction and homeostasis.
- Some athletes take growth hormones to build muscles.
- Control of milk secretion by oxytocin and prolactin.
- Cooperation and collaboration between groups of scientists—the International Council for the Control of Iodine Deficiency Disorders includes a number of scientists who work to eliminate the harm done by iodine deficiency.
