Study Notes
Introduction to the Endocrine System
- The endocrine system regulates homeostasis and is composed of endocrine glands that secrete hormones.
- Hormones circulate through the bloodstream and bind with target cells to elicit a specific body response.
- The endocrine system has four general functions: regulating growth and metabolism, maintaining homeostasis, controlling digestive activities, and controlling reproductive processes.
- The endocrine and nervous systems work together to control homeostasis.
- Water-soluble hormones bind to cell surface receptors and activate second messenger systems, producing faster effects than lipid-soluble hormones.
- Lipid-soluble hormones bind to intracellular receptors and may take several hours to days to take effect.
- Hormone secretion is controlled by hormonal, humoral, and nervous system methods.
- Hormones only interact with cells containing complementary receptors.
- Lipid-soluble hormones alter protein synthesis patterns and cell structure or metabolic activities.
- Water-soluble hormones activate or inhibit enzymatic activity, stimulate cell growth and muscle contraction or relaxation.
- The degree of a target cell's response to a hormone depends on the number and affinity of receptors, concentration of the hormone, and hormone interactions at the target cell.
- Cells may increase or decrease the number of receptors available through up-regulation or down-regulation.
