reflexes

• 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.

• 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
