Show Answers:

  1. Structure Divisions of the Nervous System
    • Central Nervous System(CNS)
    • Peripheral Nervous System
    • Voluntary Nervous System
  2. Spinal Column(Vertebral Column)
    The 33 vertebrae that enclose and protect the spinal cord
  3. Vertebrae
    • Bony segments of the spinal column
    • Body of a vertebra is the bulky portion that faces anteriorly in the spinal column
  4. Disk
    • Fluid-filled cartilage pad between vertebrae.
    • Shock absorber
  5. Cervical Spine
    The first seven vertebrae; the neck
  6. Thoracic Spine
    The 12 vertebrae that compromise the upper back.
  7. Lumbar Spine
    The 5 vertebrae that from the lower back
  8. Sacral Spine
    The 5 fused vertebrae at the posterior pelvis
  9. Coccyx
    The 4 fused vertebrae that form the lower end of the spine; the tailbone
  10. Spinal Cord
    • Nervous tissue that extends from the brain to level L2 within spinal column
    • The motor tracts carry impulses down the spinal cord and out to the muscles.
    • Pain tracts carry impulses from pain receptors up the spinal cord to the brain
    • Light touch tracts are tested by applying light touch to the patient.
  11. Spinal Column Injury
    An injury to one or more vertebrae
  12. Spinal Cord injury
    Damage to the nervous tissue of the spinal cord
  13. Complete Spinal Cord Injury
    Spinal cord injury causing complete loss of motor, sensory, and autonomic function below the level of injury
  14. Spinal Shock
    Paralysis, loss of sensation, and possible vasodilation caused by spinal cord injury
  15. Priapism
    A persistent erection of the penis
  16. Neurogenic Hypotension
    Vasodilation and relative hypovolemia caused by spinal cord injury
  17. Incomplete Spinal Cord Injury
    Injury to some but not all spinal cord tracts so that some functions are lost and some are intact.
  18. Central Cord Syndrome
    Loss of function in upper extremities from central cord injury
  19. Anterior Cord Syndrome
    Loss of most function below site of anterior cord injury
  20. Brown-Sequard Syndrome
    Loss of different functions on opposite sides of the body from injury to one side of the spinal cord
