  • Receptor cells are cells that detect stimuli.
  • Effectors bring about responses to bring the conditions in the body back to optimum level.
  • Effectors are muscles or glands.
  • Coordination centres process the information received from receptors.
  • Sensory neurons carry information as electrical impulses from receptors to the CNS.
  • Motor neurons carry electrical impulses from the CNS to effectors.
  • Effectors are all the muscles and glands which respond to nervous impulses.
  • Synapses connect neurons.
  • Nerves signals are transferred chemically across synapses.
  • Chemicals transfers through synapses set off new electrical signals in the next neuron.
  • The CNS stands for central nervous system.
  • The CNS consists of your brain, spinal cord and the nerves running from the CNS.
  • The CNS receives information from receptors.
  • The CNS is the coordination centre.
  • The passage of information in a reflex is called the reflex arc.
  • Reflexes are rapid and automatic.
  • Reflexes do not involve the conscious part of your brain.
  • Chemicals diffuse across the gap in synapses.

  • Chemicals diffuse across the gap in synapses.
  • The nervous system is made up of motor neurons, sensory neurons, effectors and the CNS.
  • What are the chemicals released at a synapse called?

    neurotransmitters
  • What are axons surrounded by?
    a layer of fatty cells called a myelin sheath
  • What does a myelin sheath do?
    Insulates electrical impulses
