  • Hormone system = Chemical impulses
  • Nervous system = Electrical impulses
  • Glands are produced by hormones. Hormones are transported by blood

Relflex Actions: In order

  • Receptor- detects stimulus (pain)
  • sensory neurone- transmits the impulse
  • Relay neurone- passes the impulse on
  • motor neurone- stimulated
  • Impulse- sent to the effector (muscle/gland)
  • Actin is taken (move etc.)

Chemicals transmit the impulse across a synapse
