MOVEMENTS <strong>OF</strong> <strong>VERTEBRAE</strong> IN DIFFERENT REGIONS-<br />

Determined by orientations of articular facets<br />

a. CERVICAL (C3-C7)-<br />

permit considerable flexionextension,<br />

lateral flexion,<br />

rotation - useful-move head<br />

b. THORACIC<br />

permit some rotation – little or<br />

no flex-extend (also limited by<br />

ribs); useful- no flex down on<br />

heart, lungs<br />

c. LUMBAR<br />

permit flex-extend, little or no<br />

rotation; useful- help increase<br />

abdominal pressure;<br />

dangerous- increase load<br />

pressure on vertebral discs<br />

Cervical (C3-C7)-facets angled<br />

superiorly and medially<br />

Thoracic - facets in coronal plane<br />

Lumbar- facets in sagittal plane
