  • Receptor cells

    • Cells that detect a stimulus (changes in the environment)
    • Receptor cells in the skin detect changes in touch, pressure, pain and temperature
    • Light sensitive cells in the retina of the eye detect changes in light and colour
    • Receptor cells in the nose detect chemicals in the air
    • Receptor cells in the tongue detect chemicals in food
    • Receptor cells in the inner ear detect changes in sound
  • Receptor cells are in the skin, nose, tongue, inner ear, and retina
  • Coordination centres

    • Brain
    • Spinal cord
    • Pancreas
  • Brain

    • Coordinates information from the receptor cells and sends signals to the muscles and glands
  • Spinal cord

    • Coordinates messages from the brain and receptor cells and coordinates reflexes
  • Pancreas

    • Coordinates the glucose levels in the blood
  • Effectors

    Muscles or glands in the body that produce a response to restore optimum levels in the body
  • Effectors

    • A muscle contracting to lift a leg
