Lesson Title: Today we are learning about
How does a body respond to a stimulus?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Information from receptors passes along cells (neurones) as electrical impulses to the central nervous system (CNS).
  2. The CNS is the brain and spinal cord.
  3. The CNS coordinates the response of effectors which may be muscles contracting or glands secreting hormones.
  4. Stimulus --> Receptor --> Coordinator --> Effector --> Response
  5. Be able to explain how the various structures in a reflex arc including the sensory neurone, synapse, relay neurone and motor neurone relate to their function.
  6. Students should understand why reflex actions are important.
  7. Reflex actions are automatic and rapid; they do not involve the conscious part of the brain.
  8. Be able to extract and interpret data from graphs, charts and tables, about the functioning of the nervous system.
  9. Be able to translate information about reaction times between numerical and graphical forms.

Keywords:
  • Hormones: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs. (1)
  • Central Nervous System: The part of the nervous system made up of the brain and spinal cord. (1)
  • Impulse: The signal that travels along the length of a nerve fiber. (1)
  • Neurone: a specialized cell transmitting nerve impulses; a nerve cell. (1)

AFL/Key Questions:
  1. How is information transmitted in the nervous system?
    Information from receptors passes along cells (neurones) as electrical impulses to the central nervous system (CNS).
  2. What is in the central nervous system?
    The CNS is the brain and spinal cord.
  3. What is the role of the central nervous system?
    The CNS coordinates the response of effectors which may be muscles contracting or glands secreting hormones.
  4. What are the stages of the reflex arc?
    The stages of the reflex arc are stimulus, receptor, sensory, relay, motor, effector then response.
  5. How are the neurones adapted to their function?
    Neurones axon allowing impulses to be transmitted long distances, they also have dendrites on the cell body which are branched to detect impulses from other nerves. They are insulated with a myelin (fatty) sheath so that impulses do not cross over and they have a synapse to propagate the impulses using chemical messengers.
  6. Why are reflex actions so important?
    They allow us to respond to our environment and keep ourselves out of danger.
  7. How are reflex actions described?
    Reflex actions are automatic and rapid; they do not involve the conscious part of the brain.

Starter Activity Differentiation and Challenge question/task
  • Students to copy and complete the keywords.
  • Teacher reveals missing letters; Students correct mistakes;
  • Discuss the scientific meanings of the words.
  • Students to write down the definitions of the most important / new keywords.
  • Discuss the 'Memory Anchor'.
    • What does it show?
    • How does it relate to the what we are learning about today (title)?
Think about PACE – Develop, consolidate and deepen knowledge, skills and understanding
