1. September 13, 2011 Warm Up 1. Take out Journal 2. Write / Answer question below What controls your body? What system does it belong to? http://www.youtube.com/watch?v=Li5nMsXg1Lk&feature=player_detailpage#t=23s

2. Foldable Fold one hot dog fold (tall and skinny) Fold one hot dog fold (tall and skinny) Make “Bracelet” or “Burrito” fold (see teacher example) Make “Bracelet” or “Burrito” fold (see teacher example) Glue on both long sides of paper only Glue on both long sides of paper only Glue into journal Glue into journal Cut up center crease, fold back both sides Cut up center crease, fold back both sides Cut on creases to create doors / flaps Cut on creases to create doors / flaps Label as seen on next slide Label as seen on next slide

6. Main Function: Main Function: This communication system controls and coordinates functions throughout the body and responds to internal and external stimuli. Our nervous system allows us to feel pain.

7. Consists of: brain, spinal cord, nerves and sense organs Sense Organs: Eyes, Skin, Ears, Nose & Tongue

8. brain Spinal Cord Cerebellum Cerebrum Medulla Oblongata Consists of: Brain and Spinal Cord Its function is to interpret, store, and respond to information received from inside and outside.

9. CerebrumVoluntary or conscious activities of the body-learning, judgment CerebellumCoordinates and balances the actions of the muscles Medulla Oblongata (Brain Stem) Controls involuntary actions like blood pressure, heart rate, breathing, and swallowing Spinal Cord The main communications link between the brain and the rest of the body

10. Cerebrum Voluntary or conscious activities of the body-learning, judgment

11. Cerebellum Coordinates and balances the actions of the muscles

12. Medulla Oblongata (Brain Stem) Controls involuntary actions like blood pressure, heart rate, breathing, and swallowing Brain Stem

13. Consists of: Sensory division and Motor division -includes all sensory neurons, motor neurons, and sense organs

14. A nerve is an organ containing a bundle of nerve cells called neurons. Neurons carry electrical messages called impulses throughout the body. Neurons are able to respond to stimuli (such as touch, sound, light, and so on), conduct impulses, and communicate with each other (and with other types of cells like muscle cells). Picture shows hundreds of severed neuron axons

15. cell body muscle tissue TYPICAL MOTOR NEURON Axon dendrite synapse cell body

16. Parts of a Neuron 1. Cell body: contains nucleus & most of the cytoplasm 2. Dendrites: projections that bring impulses into the neuron to the cell body. 3. Axon: long projection that carries impulses away from cell body 1 3 2

17. Label your Diagram of the nervous system in your foldable.

18. Finish Foldable Draw examples of each vocabulary word on front cover of foldable Draw examples of each vocabulary word on front cover of foldable
