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.
