1. Co-ordination

2. We have discovered how the digestive system , heart and lungs work together to provide the energy needed for muscle movement . What else do you need, to be able to move and respond to the environment around you?

3. All the organs and systems in a healthy human body work together to carry out functions essential to life. We need: Co-ordination ______ ______ To pick up information from our surroundings. ______ ______ _______ To process information received. Muscles, glands _________________ _________________ Notes

4. Structure of the Eye Cornea Pupil Iris Lens Retina Fovea Optic nerve Blind spot Vitreous humour

6. Optical Illusions Have a look at some of these visual phenomena. But not too long or you’ll feel sick!!! Activity

7. Pupil Size Dim Light Pupil dilates Bright Light Pupil contracts

8. Focusing Distant focus Close focus

9. Binocular Vision Notes -Stick in your copy of the diagram. -Use the text book to label and explain the diagram

10. middle ear bones Structure of the Ear outer ear (air filled) middle ear (air filled) inner ear (fluid filled) auditory canal hammer anvil stirrup semi-circular canals auditory nerve cochlea oval window ear drum

12. Activity In pairs (you need a safety catcher!!): 1. Stand on one leg and count till you lose balance. How many seconds did you manage? 2. Stand on one leg again but this time with your eyes closed. Your friend can make sure you don’t fall over. How many seconds did you last this time? Why do you think this happened?

14. The Nervous System Brain, spinal cord and nerve fibres communicating with sense organs, muscles, glands and internal organs

15. Copy and complete the diagram above. Notes The Flow of Information CNS C____ N____ S______ Includes: Sense organs have r____ : e.g. Effectors Bring about response e.g nerves nerves Help Success Guide p70

16. Nerve Cells (neurones) Sensory neurons Carry information from sense organs to CNS. Use the cut out sheet and the following slides to make your own diagrams and notes. Receptor Sensory fibre Axon fibre Cell body with nucleus Impulses to CNS Notes

17. Relay neurons Connect neurones. Receive information from sensory neurones and transmit to motor neurones. Impulses from sensory neurone Impulses to other neurones Cell body with nucleus Main relay fibre

18. Motor neurons Carry information from CNS to muscles and glands. Effector: Muscle or gland Cell body with nucleus Axon fibre Impulses from CNS

20. Neurones and the Reflex Arc Sensory neurone cell body Sensory Fibre Motor Fibre Response Nerve ending in receptor e.g in muscle CNS Synapse Motor neurone cell body Relay neurone cell body Stimulus Nerve ending in receptor e.g in skin

21. Reflex Arc Label your copy of the reflex arc. CNS Notes Help Torrance p169

22. The Reflex Action Motor neurone Spinal Cord Sensory neurone Motor neurone Relay neurone

23. Reflex action animation Using an example of your choice e.g heat, standing on a tac etc., describe how impulses are picked up and sent around the reflex arc. Should include: -order neurones passed through -receptor and effector -how the reflex action protects the body Notes Help Torrance p169 Success Guide p71

24. The Brain Skull Cerebrum Cerebellum Medulla Spinal cord Hypothalamus Pituitary gland

25. Cerebrum, cerebellum and medulla -Label your diagram of the brain -For each of the brain areas above, describe what they control. The Brain Notes
