As Musculi multifidi (singular musculus multifidus , from lat much split manifold;. "Feathered much muscles") refers to short, three spinal segments running, rope-like skeletal muscles . They belong to the autochthonous back muscles , stabilize the spine on a segmental level and are found in all mammals.
This muscle group extends from the sacrum to the second cervical vertebra , whereby regional subgroups can be formed:
- The multifidi sacrales muscles arise from the sacrum, the iliac bone and the sinewy structures of the region.
- The multifidi lumbales muscles arise from the teat processes of the lumbar vertebrae .
- The multifidi thoracic muscles arise from the transverse processes of the thoracic vertebrae .
- The multifidi cervicis muscles arise from the articular processes of the 4th to 7th cervical vertebrae .
They find their starting point at the spinous process of the preceding vertebra.
