Across
  1. 2. Mixed nerve carrying both sensory and motor fibers in the PNS, right outside the vertebral foramen.
  2. 6. Carries pain, temperature, and crude touch sensations from dermatomes toward the supraspinal areas
  3. 7. Carry axons involved in the sympathetic nervous system from spinal nerves to and from the sympathetic trunk.
  4. 10. Spinal Cord Blood Supply
  5. 11. Grey Matter part of the spinal cord which processes sensory and motor information related to the body
  6. 12. Houses cell bodies of sensory neurons of somatic and autonomic systems.
  7. 15. White Matter part of the spinal cord which carries information to/from the spinal cord for sensory, motor, and autonomic functions related to the body
  8. 16. Conveys fine touch, vibration, and proprioception fibers from dermatomes toward the supraspinal areas
  9. 19. Group of tracts which convey unconscious proprioceptive and motor feedback information to the cerebellum.
  10. 20. Provides nutrients to deep spinal cord and allows passage of CSF between the fourth ventricle and the spinal cord levels.
  11. 21. These gelatinous-like structures of the vertebral column borders the anterior surface of the Central Canal, and can protrude into it to cause central signs and symptoms. "Vertebral _____"
  12. 23. Axons transmitting motor commands from the spinal cord towards peripheral targets. Contains both somatic and sympathetic axons.
  13. 26. Collection of Neurons in the PNS, located on the outside of vertebral bodies, involved in the sympathetic nervous system
  14. 27. This white matter area carries a combination of sensory axons (Spinocerebellar and Anterolateral) and motor axons for extremity movements (Corticospinal) vertically within the spinal cord
  15. 28. Controls voluntary motor movements of the extremities via upper motor neurons. The most important tract to know for movement.
  16. 29. The tapered end of the spinal cord at the L1 vertebral body level.
Down
  1. 1. Supplies the lateral and anterior trunk and limb dermatome and myotome patterns.
  2. 3. This white matter area includes sensory axons (DCML) and is the portion of the spinal cord closest to the vertebral arch and spinous process
  3. 4. Opening within the vertebrae for spinal nerves to enter and exit.
  4. 5. Axons carrying sensory information into the spinal cord from peripheral sensory receptors.
  5. 8. Forms the posterior boundary of the vertebral foramen, bordering the posterior surface of the Central Canal. "Vertebral _____"
  6. 9. Group of spinal tracts which modulate and refine movement by providing unconscious motor control of the body, mainly the trunk and proximal limbs
  7. 13. Vertical arrangement of sympathetic ganglia along the entire vertebral column, Part of the autonomic nervous system, regulates body functions for "Fight or Flight" responses.
  8. 14. Gray Matter sympathetic neuron cell bodies sending sympathetic outflow to the body. One of the three horns of the spinal cord, only present from T1-L2.
  9. 17. Bundle of nerve roots travelling vertically within the central canal from L1 to S5 vertebral levels
  10. 18. Contains lower motor neurons that innervate skeletal muscles of the body. One of the the three horns of the spinal cord.
  11. 21. Supplies the posterior trunk and back muscle dermatome and myotome patterns.
  12. 22. This white matter area is carries mostly motor axons for trunk and posture (extra-pyramidal) and some sensory axons (Anterolateral), and is the portion of the spinal cord closest to the vertebral bodies and discs of the skeletal system.
  13. 24. Gray Matter sensory neurons receiving sensory information from the body. One of the three horns of the spinal cord.
  14. 25. Transmits neural signals between the brain and body.
