Dependent Variable- The variable being studied in the experiment; it is expected to change when the independent variable is changed. Thus, a typical experiment will examine the effects of the independent variable on the dependent variable.
Articular processes: These processes form joints between successive vertebrae. The superior and inferior articular processes arise from the same junctions as the transverse processes (one superior and one inferior process on each side), and each process has an articular surface called a facet.
Side view of the cervical spine showing the facet joint. X-ray [CT scan] showing the facet joint in cross-section. Paraspinal Muscles. The spine is formed by the bones (vertebral bodies), which are stacked one on top of another. On each side of the vertebral bodies, are tiny joints called facet joints. Arthritic changes and inflammation can develop in these joints, and the nerves to the facet joints can convey severe and diffuse pain.
