Document Summary
Instruct patient to move jaw forward and laterally against your resistance and open mouth against your resistance. Composed of 33 stacked vertebrae (7 cervical,12 thoracic, 5 lumbar, 5 sacral and 3-4 coccygeal vertebrae) Curvatures and intervertebral discs allow spine to absorb great deal of shock. 4 curvatures: cervical curvature (concave posteriorly, thoracic curvature (convex posteriorly, lumbar curvature (concave posteriorly, sacrococcygeal curvature (convex posteriorly) Intervertebral discs: elastic fibrocartilaginous plates that cushion the spine like a shock absorber and help it move. If compression is too strong, nucleus pulposus in centre can herniate out of vertebral column and compress spinal nerves and cause pain. Spinous processes: found in furrow down midline of back. C7 and t1: found at base of neck. Paravertebral muscles: found mounded on each side of spinous processes. Spine is straight and head is erect and not erected to one side. Palpate spinous processes, sternomastoid, trapezius and paravertebral muscles. Symmetrical, firm, no muscle spasm, no pain/tenderness (ask)
