Endocrine system overview

  1. 1. Construct your Interactive Notes • • • • • Staple 6 pages of binder paper to the cover On the cover, write Chapter 9: Endocrine System Name, Period, Seat # A color picture
  2. 2. Endocrine System Overview (pg 2) • The endocrine system produces hormones, which travel through the bloodstream and regulate body processes
  3. 3. Endocrine System Overview (pg 2) • The endocrine system produces hormones, which travel through the bloodstream and regulate body processes • The system consists of 8 glands scattered throughout the body
  4. 4. Endocrine System Overview (pg 2) • The endocrine system produces hormones, which travel through the bloodstream and regulate body processes • The system consists of 8 glands scattered throughout the body • The only system in the body where the organs that make up the system are not in physical contact with one another
  5. 5. Hormones • A chemical substance that regulates the metabolic activity of other cells in the body
  6. 6. Hormones • A chemical substance that regulates the metabolic activity of other cells in the body • Control many body processes, including – growth and development – maintaining water, electrolyte, and nutrient balance in the blood – Regulating cellular metabolism
  7. 7. Types of Hormones 1. Proteins: Made of amino acids. Most common type of hormone
  8. 8. Types of Hormones 1. Proteins: Made of amino acids. Most common type of hormone 2. Steroid Hormones: Made from cholesterol. Includes sex hormones and hormones produced by the adrenal cortex
  9. 9. Types of Hormones 1. Proteins: Made of amino acids. Most common type of hormone 2. Steroid Hormones: Made from cholesterol. Includes sex hormones and hormones produced by the adrenal cortex 3. Prostaglandins: Made of lipids released from cell membranes. Act locally
  10. 10. Hormone Action • Because they circulate in the bloodstream, hormones reach all organs in the body, but they only affect cells that have receptors for that particular hormone. These are called target cells.
  11. 11. Hormone Action • Because they circulate in the bloodstream, hormones reach all organs in the body, but they only affect cells that have receptors for that particular hormone. These are called target cells. • Hormones cause one or more of the following changes in the target cells 1. Change the permeability of the plasma membrane 2. Activate protein synthesis 3. Activate or deactivate enzymes 4. Stimulate mitosis (cell division) 5. Increase secretion
  12. 12. Control of Hormone Release 1. Hormonal stimuli: A gland is stimulated to release hormone by another hormone. For example, hormones from the hypothalamus stimulate the pituitary gland
  13. 13. Control of Hormone Release 1. Hormonal stimuli: A gland is stimulated to release hormone by another hormone. For example, hormones from the hypothalamus stimulate the pituitary gland 2. Humoral stimuli: Changing levels of ions or nutrients in the blood stimulate hormone release. For example, low blood calcium levels stimulate release of parathyroid hormone
  14. 14. Control of Hormone Release 1. Hormonal stimuli: A gland is stimulated to release hormone by another hormone. For example, hormones from the hypothalamus stimulate the pituitary gland 2. Humoral stimuli: Changing levels of ions or nutrients in the blood stimulate hormone release. For example, low blood calcium levels stimulate release of parathyroid hormone 3. Neural stimuli: Nerve fibers stimulate hormone release. Occurs in the adrenal medulla
