Multifidus
Extracted from the Wikipedia article Multifidus muscle.
The multifidus (multifidus spinae; pl.: multifidi) muscle consists of 23 muscle fasciculi, which fill up the gutter on either side of the spinous processes of the vertebrae (the so-called spino-transverse groove), 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 transversospinalis set.
