  1. What bony landmarks can you use to locate the specific vertebral levels?
    • Illiac crest—in between in the L4 spinous process
    • Inferior angle of the scapula—spinous process of T7
    • Medial end of Spine of scapula—T3
    • C7 can palpate
  2. Which branches of spinal nerves gives sensory innervation to the skin of ENTIRE back?
    Both dorsal and ventral rami
  3. What part of the back is supplied by the dorsal rami?
    Medial 2/3
  4. What else do dorsal rami innervate?
    • The deep back muscle—erector spinae
    • Zyaphopheal(facet) joints
    • Posterior most ligaments on the spinal column
  5. Functional difference between dorsal ramus and dorsa root?
    • Root—only contains sensory fibers(afferent)
    • Ramus—mixed and has both afferent and efferent
  6. Flexed position start, bring upright. What is this called?
    Shortening. Concentric contraction
  7. Contraction in deep back muscles during flexion?
    Eccentric Contraction
  8. Contraction that occurs in deep back muscles in partially flex position?
    Isometric—same length
  9. Contraction during lateral bending…
    • Ipsilateral shortening contraction
    • Contralateral lengthening contraction
  10. Define “lesion”—a structural or functional abnormality
    • Nerve Lesion:
    • 1) irritative lesions. Motor syptoms—muscle spasms. Sensory—pain, abnormal heat sensation, prickly, tingly
    • 2) Destructive lesions. Motor symptoms—muscle weakness or paralysis. Sensory—Numbness, loss of sensation
  11. In lumbar region, where is spinal nerve located within the IF?
    The top
  12. How does the anterior boundary of the intervertebral foramina differ at lumber and cervical levels?
    • Disc in lumbar is in loser half of anterior boundary
    • More center in cervical region
  13. Location of spinal nerves in cervical vs lumber?
    • Lumber—top of foreman.
    • Cervical—center of foreman
  14. *On patient’s CT, see lesion in the foramen—facet joint disease causing lateral stenosis
    • At T11-T12, hypertrophy, a bit of bulging disk.
    • Intervertebral foramen becoming smaller.
    • Could cause pressure on spinal nerve
