1. Central Nervous Brain and spinal cord
System Integration control center
2. Peripheral Ner- Outside CNS
vous System Consists mainly of nerves that extend from brain and spinal cord
3. Spinal Nerves To and from spinal cord
4. Cranial Nerves To and from brain
5. Somatic Sensory Convey impulses from skin, skeletal muscles and joints to CNS
Fibers
6. Visceral Sensory Convey impulses from visceral organs to CNS
Fibers
7. Glial Cells One of a variety of cells that provide a framework of tissue that supports the
neurons and their activities
8. Neurons Cells that transmit chemical signals throughout the nervous system
9. Gray Matter The regions with many cell bodies and dendrites
10. White Matter The regions with many axons
11. Myelin Lipid-rich substance that insulates the axons, produced by glial cells
12. Nucleus A localized collection of neuron cell bodies in the CNS
13. Ganglion A cluster of neuron cell bodies in the PNS
14. Tract A bundle of axons found in the CNS
15. Nerve A bundle of axons found in the PNS

16. Integration The process of combining sensory perception and higher cognitive functions such
as memories, learning, and emotion to produce a response
17. Somatic Nervous Responsible for conscious perception and voluntary muscle control
System
18. Autonomic Ner- Responsible for involuntary corn of the body and maintenance of homeostasis
vous System
19. Enteric Nervous Responsible for controlling the smooth muscle and glandular tissue of digestive
System system
20. Axon Hillock Where the axon emerges from the cell body
21. Axoplasm Cytoplasm inside the axon
22. Axon Segment Length of axon covered by myelin
23. Unipolar Cells One process emerging from neuronal cell body
Exclusively sensory neurons
Cell bodies always found in ganglion
24. Bipolar Cells Have two processes which extend from each end of the cell body
Found mainly in the olfactory epithelium and retina
25. Multipolar Cells Have one axon and two or more dendrites
99% of the neurons in the body
26. Astrocyte CNS; star shaped support cells, many processes, maintain concentration of chem-
icals in extracellular space, contribute to blood-brain barrier
