CONTROL OF SELF-REGULATING SYSTEMS

Cards (4)

  • SELF-REGULATING SYSTEM CONTROL?
    1. INPUT: change to system
    2. RECEPTOR: detects change
    3. COORDINATOR: stores operational information/ coordinates effectors
    4. EFFECTOR: brings about a change, causing a return to optimum
    5. OUTPUT: back to optimum
    6. FEEDBACK LOOP
  • HOW ARE CONTROL MECHANISMS COORDINATED?
    negative feedback or positive feedback
  • WHAT IS NEGATIVE FEEDBACK?
    change produced by control system causing a change in stimulus detected by the receptors, turning the system off
  • WHAT IS POSITIVE FEEDBACK?
    deviation from optimum that causes changes leading to a greater deviation from normal
