Which set correctly lists the five structures that make up the pillar?

• A. Shoulder/Scap, Lumbar Spine, Cervical Spine, Hips, Pelvis
• B. Shoulder/Scap, Lumbar Spine, Thoracic Spine, Knees, Pelvis
• C. Shoulder/Scap, Thoracic Spine, Hips, Pelvis, Neck
• D. Shoulder/Scap, Lumbar Spine, Thoracic Spine, Hips, Pelvis

Answer: (D)

The pillar is made up of five structures that provide stability and transfer forces between the upper and lower body: the shoulder/scapular region, the thoracic spine, the lumbar spine, the hips, and the pelvis. The correct set includes all five of these components, pairing the two spine regions with the shoulder girdle and the hips/pelvis. It intentionally excludes the neck (cervical spine) and the knees, which aren’t considered part of this pillar framework. Having these five elements together keeps the stabilizing chain complete, making this option the best fit.
