1. Sending a Message
The communication system of our bodies is not entirely different from a telephone communication system.

3. Electrochemical Network 11/29/2010
Neuron: The basic functional cells of the brain and nervous system.
Designed to transmit information from place to place throughout the body.

5. Neurons
Neurons are made up of three basic parts.
Cell body- the operation center of the cell which contains the cell’s nucleus.
Dendrites- extend from the cell body and receive incoming messages.
Hint: Dendro=tree (Greek)

6. Terminal Fibers- Ending of the axon where the synapses are located.
Axon- Part of the neuron that carries messages away from the cell body and to another neuron.
Hint: Axon=Away
Terminal Fibers- Ending of the axon where the synapses are located.
Hint: Terminal=end (terminal patient)

7. Receptor- Protein in a neuron that neurotransmitter binds to.
Neurotransmitter- Chemical messenger that communicate the signal to the next neuron.
Hint: Transfer between neurons
Receptor- Protein in a neuron that neurotransmitter binds to.

9. Neurons and Transmitters
Neurons constantly carry information throughout the brain and body.
They pass electrical messages from one to another without touching.
The axon of one neuron and the dendrite of another are separated by synapses

10. Passing the message
By the use of spinal motor neurons, consists of a cell body and a long thin axon covered by myelin.
Around the cell body is a branching dendrite tree that receives signals from other neurons.

11. Parts of the Nervous System
Brain: Command Center
Spinal Cord: Receives and
transports the messages
