1. Nuerolimma: outermost layer of schwann cells
2. Nodes: gaps between schwann cells
3. Oligodendrocyte: forms myelin sheath in cns.
4. Schwann cells: help injured nuerons regenerate
5. White fibers: myelinated axons found in the white matter of the
brain and spinal cord.
6. Gray matter cells: not covered by myelin
7. Sensory (afferent) neurons: carry impulses to spinal cord and
brain
8. Motor (efferent) nuerons: carry impulses from the cns to muscles
and glands

9. interneurons (central or association): carry impulses from place
to place within cns
10. Nerve: fiber bundle in pns
11. Tract: nerve bundle in cns
12. Endoneurium: surrounds each individual fiber
13. Perineurium: surrounds each fascicle
14. Epineurium: surrounds the whole nerve
15. Sensory (afferent) nerves: cranial nerves that consists of sensory
fibers and only send impulses to the brain.
16. Motor (efferent) nerves: cranial nerves that contain motor fibers
and only take impulses away from the brain.
17. Mixed nerves: most cranial and all spinal nerves. Contain both
sensory and motor nerves
18. Neroglia (glial) cells: 90% of cns and pns. Support cells. I.e.
schwann cells
19. Astrocytes: star-shaped cells. Nourish, physically support, and
anchor nuerons.
