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.
In the eleventh thoracic vertebra the body approaches in its form and size to that of the lumbar vertebrae. The articular facets for the heads of the ribs are of large size, and placed chiefly on the pedicles, which are thicker and stronger in this and the next vertebra than in any other part of the thoracic region. The spinous process is short, and nearly horizontal in direction.
