Multiple Choice

The multifidus muscle originates from which structure?

Explanation:
The multifidus is a deep spine stabilizer that runs from the transverse processes of the vertebrae up to the spinous processes a few levels higher. This origin-insertion pattern—origin on the transverse processes across the spine and insertion on more superior spinous processes—lets it span multiple segments and help stabilize the vertebral column during movement. The spinous processes serve as insertion points for this muscle, not its origin, which is why originating from the transverse processes is the correct choice. The articular processes aren’t the typical origin, and the iliac crest is associated with other back muscles, not the multifidus.
