1. Nervous Tissue Specialized for conduction of electrical impulses
98% of nerve tissue is found in brain/spinal cord

2. Types of Nerve Cells Nervous tissue is made of 2 types of nerve cells
1. Neurons
Conscious/unconscious thought processes
Can be up to 1 meter in length (39 inches)
Limited ability to repair themselves
Cellular characteristics of neurons
Cell body -main body contains nucleus
Dendrites -receive information
Axon -carries information away from cell

3. Types of Nerve Cells
2. Neuroglial cells (neuroglia)-cells that surround neurons
Support neurons physically
Repair tissue framework
Destroy invading microorganisms
Provide nutrients for neurons
Regulate neuronal environment

5. Cell Body of motor neuron
