  1. What makes up the CNS?
    Brain and spinal cord.
  2. What makes up the PNS system?
    Crainial nerves, spinal nerves, and ganglia.
  3. Sensory neuron
    Also known as afferent, these are our 5 senses and carry impulses into CNS.
  4. Motror neuron
    Also known as efferent, these send signals to move our bodies. They carry impulses away from the CNS.
  5. Interneuon
    Also known as associate neurons, these carry impulses within the CNS.
  6. Nueroglia cells
    Support cells of the CNS that are non-conductive
  7. Astrocytes
    Part of the CNS, these are large branching cells that form the blood brain barrier.
  8. Oligodendrocytes
    (OLLIE-GO-DEN-DRO-SITES) Part of the CNS, cells with few branches that form myelin.
  9. Microglia
    Part of the CNS, these are ciliated and secrete CSF.
  10. Neurolemmocyte
    Part of the PNS, these are myelin producing and surround the axon.
  11. Satellite cells
    Part of the PNS, these isolate and nourish cell bodies in ganglion.
  12. What is the red quesion mark?
    Nerve cell
  13. What is the red question mark?
    Epineurium
  14. What is the red question mark?
    Fasicle or faciculus
  15. What is the red question mark?
    Perineurium
  16. What is the red question mark?
    Endoneurium
  17. What is the red question mark?
    Dura mater, the tough outer layer that consists of the periosteal layer and meningeal layer
  18. What is the red question mark?
    Periosteal layer
  19. What is the red question mark?
    Periosteal layer
  20. What is the red question mark?
    Arachmnoid membrane
  21. What is the red question mark?
    Pia mater
  22. Cervical plexus
    Located on cervical spine lateral to C1- C4. The fifth cervical spinal nerve is not part of the cervical plexus.
  23. Brachial plexus
    Spinal nerves C5 - T1. Extend laterally from the neck, and continue to the axilla
  24. Lumbar plexus
    Spinal nerves L1 - L4. Located laterally to the L1 - L4 vertebrae.
  25. Sacral plexus
    Contains your sciatic nerve and is located immeadiately inferior to the lumbar plexus.
  26. Sciatic nerve
    Also known as the ischiadic nerve. It's the largest and longest nerve in the body. It projects from the pelvis through the greater sciatic notch of the os coaxae and extends into posterior region of thigh.
  27. Sympathetic trunk
    The sympathetic trunks are a paired bundle of nerve fibers that run from the base of the skull to the coccyx.
  28. Sympathetic ganglion
    Deliver information to the body about stress and impending danger, and are responsible for the familiar fight-or-flight response.
  29. Cauda Equina
    The cauda equina is a structure within the lower end of the spinal column of most vertebrates, that consists of nerve roots and rootlets from above.
  30. Filum terminale
    Delicate strand of fibrous tissue, about 20 cm. in length, proceeding downward from the apex of the conus medullaris.
