Multifidus muscle

The multifidus (multifidus spinae : pl. multifidi ) muscle consists of a number of fleshy and tendinous fasciculi, which fill up the groove on either side of the spinous processes of the vertebrae, from the sacrum to the axis. While very thin, the Multifidus muscle plays an important role in stabilizing the joints within the spine. The multifidus is one of the transversospinales.The posterior divisions of the sacral nerves.The multifidus muscles (labeled left) as seen in a posterior view of the neck.
