Document Summary

Kyphosis anteriorly concave curvature of the vertebral column. Occurs normally in thoracic and sacral regions. Abnormal exaggeration occurs in the thoracic region. Lordosis anteriorly convex curvature of vertebral column. Occurs normally in cervical and lumbar regions. Abnormal exaggeration usually occurs in lumbar region. Scoliosis abnormal lateral curvature of the spine. Primary curvature anything that is kyphotic (thoracic, sacral) Early in development all curvature is kyphotic. Secondary curvature anything that is lordotic (cervical, lumbar) This curvature is associated with weight bearing. First to develop is lumbar (right around birth) Pedicle attaches directly to vertebral body. Lamina connects pedicle to spinous process. Vertebral foramen = lamina + pedicle + vertebral body. Zygapophyseal joint superior articular process + inferior articular process from above. One on each side of the spinous process. Superior vertebral notch + inferior vertebral notch = intervertebral foramen. Spinal nerve passes through intervertebral foramen (so does drg) Transverse foramen hole in transverse process where vertebral artery passes through.
