anatomy 1 thoracic and lumbar vertebra

The flashcards below were created by user merazar15 on FreezingBlue Flashcards.

  1. The bodies of the thoracic vertebra become progressively _______ as we move distally
  2. T/F. Each of the thoracic vertebra articulate with a pair of ribs
  3. The two facets of the rib articulate with the bodies of two vertebra to form the
    Costo-Vertebral Joint
  4. The tubercle of the rib articulates with the TP to form:
    type of joint:
    type of movement here:
    • Costo-Transverse Joint
    • synovial
    • permits movement of ribs during respiration
  5. movements assoc c/ thoracic spine:
    why is there only a little movement of the thoracic spine?
    • Forward flexion, Extension (very little), Lateral flexion, Rotation
    • because of the attachment of the ribs and partly because of the arrangements of the Articular Facets
  6. regarding the lumbar, superior facets face:
    inferior facets face:
    • sup: inward
    • inf: outward
  7. sacrum is formed by fusion of:
    5 vertebra
  8. sacrum curves:
  9. Dorsal surface has 2 Articular Facets which articulate with:
    with the annominate on each side to form the pelvis
  10. Posterior rami exit via:
    dorsal sacral foramina
  11. Anterior Rami exit via:
    Anterior sacral Foramina
  12. The Vertebral Canal ends at the:
    • sacral foramen
    • (shaped like an upside down V)
  13. regarding the pelvis, There is a curved, irregular articular surface of the sacrum that articulates with:
    the annominate on each side to form the pelvis
  14. massive pad of Fibrocartilage that is firmly attached to the vertebra above and below all the way around the circumference:
    Intervertebral Discs
  15. T/F:The IVD is solid enough to transmit and support the weight of the body and flexible enough  to permit movement between the vertebra’s.
  16. the IVD consists of an outer ring of tough fibrocartilage called:
    Anulus Fibrosis
  17. the IVD has a soft center that is of  gelatinous consistency called
    Nucleus Pulposis
  18. Intervertebral foramen: lateral and posterior portions of the disc makes up part of the IVF through which:
    Spinal Nerve emerges
  19. interspinous ligament runs from:
    the lower edge of one spinous process to the upper edge of the next one
  20. ligament that serves as a midline attachment for some important muscles
    supraspinous ligament
  21. supraspinatus ligament merges with what ligament and runs the whole length of the spinal column connecting the spinous processes?
    interspinous ligament
  22. The Supraspinous ligament in the cervical spine is referred to as the:
    Nuchal ligament
  23. purpose of the supraspinous ligament?
    help to “reduce flexion” of the spine
  24. structures that limit flexion of the vertebral column is a series of short ligaments that hold the lamina together:
    ligamentum flavum
  25. ligamentum flavum lies on the front of the:
  26. ligament that is made up of yellowish fibrous tissue hence its name which translates to “yellowish ligament”:
    Ligamentum flavum
  27. 2 ligaments that hold the vertebral bodies together:
    which is stronger:
    • Anterior Longitudinal Ligament
    • Posterior Longitudinal Ligament

    ALL is stronger
  28. what is the difference btwn Anterior Longitudinal Ligament and the Posterior Longitudinal Ligament?
    • ALL:
    • limits Ext of spine
    • covers front and sides of vertebral bodies
    • thick and strong
    • attached to upper and lower edges of each vertebral body
    • PLL:
    • limits flexion of spine
    • runs the back of vertebral bodies
    • its narrow longitudinally where it overlies each body & is widened out where it covers each disc
  29. Each vertebra is attached to its neighbor by:
    • Intervertebraldiscs and ligaments
    • and posterior joints
  30. Each Posterior Joint is surrounded by:
    by a Capsular Ligament that is loose enough to accommodate the movement that occurs between a set of vertebra
  31. The Capsular Ligament has no great strength but the articular processes themselves are strong because:
    • because the upper ones face forward and the lower ones face backward
    • the articular processes prevents slippage of the vertebra above forward relative to the one below
  32. The _______ permits movement and the ________ prevent slippage of the vertebra
    • Capsular Ligament
    • Articular Processes
