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.
The upper surface of a typical cervical vertebral body is concave from side to side and convex in an anterior posterior direction (fig 1). The upper projection of the lateral superior surface is known as the uncus and articulates with the vertebral body above at the uncovertebral joint of Luschka.urgery is generally used in degenerative disease for decompression of spinal cord or nerve roots. The decompression itself may lead to a relative destabilisation of the cervical spine by interference with muscle, ligament or bone.
