Which structure is the SCP for spinous wiggle?

• A. Spinous Process
• B. Transverse Process
• C. Pedicle
• D. Lamina

Answer: (B)

For a spinous wiggle, you want a contact point that gives you a precise, stable handle on the specific vertebra without being pulled off by the overlying muscles or by movement of the midline spinous process. The transverse process fits that role well. It is a palpable, lateral projection you can reliably feel at a given level, and it acts as a clear anchor point to apply gentle, localized pressure and discover subtle motion of the vertebral segment. The spinous process, while prominent, sits along the midline and is more influenced by muscular tension and overall spinal movement, making it harder to isolate a single segment with a wiggle. The lamina and pedicle are deeper and less accessible through surface palpation, so they’re not practical contact points for this maneuver. So, using the transverse process as the contact point provides the best balance of palpability, leverage, and segmental specificity for spinous wiggle.
