Nervous System

3. tracts pathways that move action potentials from one area in the CNS to another
5. part of the brain that controls balance and body motion
6. type of neuroglia that serves as the major supporting tissue in the CNS
10. Nervous System consists of all the neuron cell bodies and processes outside of the brain and spinal cord(PNS)
13. cell processes that form myelin sheaths around axons in the CNS
14. a cluster of neuron cell bodies in the PNS
16. Division prepares the person for physical activity
20. Fiber that carries messages from other neurons to the nerve cell body
