2. September 13, 2011 Warm Up 1. Take out Journal 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

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

Label as seen on next slide 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. Consists of: brain, spinal cord, nerves and sense organs Sense Organs: Eyes, Skin, Ears, Nose & Tongue Consists of: Brain and Spinal Cord Its function is to interpret, store, and respond to information

received from inside and outside. Cerebrum brai n Cerebellum Medulla Oblongata Spinal

Cerebrum Voluntary or conscious activities of the body-learning, judgment Cerebellum Coordinates and balances the actions of the muscles

Medulla Oblongata (Brain Stem) Spinal Cord Controls involuntary actions like blood pressure, heart rate, breathing, and swallowing The main communications link between the brain and the rest of the body

Cerebrum Voluntary or conscious activities of the body-learning, judgment Cerebellum Coordinates and balances the actions of the muscles Medulla Oblongata

(Brain Stem) Controls involuntary actions like blood pressure, heart rate, breathing, and swallowing Brain Stem Consists of: Sensory division

and Motor division -includes all sensory neurons, motor neurons, and sense organs 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).

muscle tissue 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
