1. What regulates the release of hormones? feedback systems 2. Positive Feedback- tells a hormone to make more 3. Negative Feedback- stops making a hormone 4. What is pumped out of the cells where ADH released from the posterior pituitary gland? Secreting Cells 5. What cells the hormones target called when ADH targets the kidney? Receiving Cells 6. Why are hormones are released? • -altered cell environment such as increases intake of glucose leads to a release of insulin • -maintaining levels of other hormones; cascades trigger the release of other hormones, ex: TRH • -neural control is when autonomic NS - not in control 7. non-steroidal hormones • -water soluble, can float around blood stream with no issues since the blood stream is made up • of water, but cannot get through phospholipid • bilayer - which is why we need receptors on the cells and second messengers like proteins that live inside the cells to help get the message to the nucleus. • Insulin freely moves around bloodstream but must connect with a second messenger. 8. Steroidal Hormones • -lipid soluble, fatty hormones floating around bloodstream cannot float around easily so they
