3. True or False: Each brain contains over a million neurons and a billion glial cells, all containing the exact same genetic material.


4. True or False: There are hundreds of "types" of neurons, classifiable by unique structural properties or by unique functional properties.


5. True or False: Glia comprise only five percent of the cells in the brain.


6. True or False: Some glial cells form myelin sheaths, which are fat wrappings (like insulation).


7. True or False: A single neuron or a group of neurons can send only one signal to another neuron or group of neurons at a time.


8. True or False: Neurons and glial cells are the "building blocks" of brain structure.


9. True or False: Specialized areas of close proximity between neurons designed for communication are called synapses.


10. True or False: A neurotransmitter is a chemical released from a neuron.
