Document Summary

Coordination and balance testing: nger to nose, gait, romberg test. Persistent headaches, blurred vision, vertigo, memory loss, irritability, decreased attentions span, ability to concentrate. Functional anatomy of the spine: structures of the vertebral column: vertebral canal: spinal cord, cauda equina (nerve roots), meninges (membranes), vessels (blood and lymph, canal (lumen, foramen): varies in its shape. L-spine, wider and triangular (for cauda equina: within canal, small fat pads ll recesses (cushions) Important in rapid movement: cord moves back and forth. Help protect tissues from sudden impact: intervertebral foramen: cross-sectional area varies (l-spine, exion increases 30% and extension decreases 20%) Rotations and side bending only change between 2-4: facet joints. Cervical facets: exion and extension, rotation, lateral exion. Lumbar facets: exion, extension, lateral exion available, rotation limited. Functional anatomy of the spine: muscles of the spine: interspinales and intertransversarii. Anatomical variations of the spine: kyphosis: accentuation of thoracic spine, rounded-shoulders but no back pain, result of overdeveloped pectoral muscles.
