  1. A sympathetic nerve carries information from the:
    visceral organs
  2. Information from a sympathetic nerve will travel through the _______ root to the _______ nuclei.
    dorsal, sensory
  3. What structures are innervated by the axons that travel through the dorsal ramus?
    the skin and skeletal muscles of the back
  4. What structures are innervated by the axons that travel through the ventral ramus?
    • ventrolateral body surface
    • structures in the body wall
    • the limbs
  5. Sensory information from the front and side of the torso travel to the sensory nuclei via the:
    ventral ramus
  6. Information collected by interoceptors, proprioceptors, and exteroceptors in/on the back of the body travel to the somatic sensory nuclei via the:
    dorsal ramus
  7. Will the white ramus contain myelinated or unmyelinated axons?
    myelinated axons
  8. True or False: The gray ramus will contain unmyelinated axons.
    True
  9. What structures are innervated by the motor axons that travel through the white ramus?
    visceral organs
  10. What structures are innervated by the motor axons that travel through the gray ramus?

  11. What structures are innervated by preganglionic fibers?
    abdominopelvic viscera
  12. What structures are innervated by postganglionic fibers?
    smooth muscles, glands, and thoracic viscera
  13. The sympathetic nerve provides innervation to the structures of the:
    thoracic cavity
  14. The white ramus is to _______ fibers as the _____ ramus is to postganglionic fibers.
    preganglionic, gray
  15. Which ramus of the spinal nerve contains preganglionic neurons and carries visceral motor fibers?
    white ramus
  16. What structure is surrounded by the epineurium?
    the entire spinal nerve
  17. What structure is surrounded by the perineurium?
    the neural fascicle
  18. What structure is surrounded by the endoneurium?
    an individual axon
  19. Where is the myelin sheath located in relationship to the endoneurium?
    it is inside (deep to) it
  20. When a preganglionic neuron combines with a postganlionic neuron you get a:
    sympathetic neuron
