Study Notes
The Endocrine System: Key Facts and Functions
- The endocrine system includes cells and tissues that produce hormones or paracrine factors.
- It functions to maintain an optimal biochemical environment, influence metabolic activities, regulate growth and development, and control sexual reproduction.
- Paracrine communication refers to chemical messengers between cells within one tissue, while hormones are chemicals secreted into the bloodstream for transport to distant target tissues.
- Up-regulation and down-regulation are processes where target cells form more or lose receptors in response to hormones.
- Tropic hormones stimulate the release of another hormone, while trophic hormones stimulate growth and nourishment of a gland.
- Stress is any condition that threatens homeostasis, and neurohormones are hormones released by neurons into the bloodstream.
- The pancreas has clusters of endocrine cells called pancreatic islets, and the hypothalamus has both neural and endocrine functions.
- The hypothalamus regulates both the nervous and endocrine systems, secretes regulatory hormones, and exerts direct neural control over the endocrine cells of the adrenal medullae.
- The pituitary gland releases nine important peptide hormones, divided into the anterior pituitary (adenohypophysis) and posterior pituitary (neurohypophysis).
- The nervous system can modify the stimulation of endocrine glands and their negative feedback mechanisms.
- Hormone concentrations in the blood reflect the rate of release and the speed of inactivation and removal from the body.
- The endocrine system is responsible for both short-term crisis management and long-term ongoing metabolic activity management.
