Insertion: Spinous processes of vertebrae (except C1), 2-4 bones above origin. Multifidus originates from the sacrum, iliac crest and erector spinae aponeurosis, and inserts into the spinous processes of each vertebra. This all depends on which treatment method is chosen for the given dysfunction. Each multifidus muscle runs from its origin to insert 2-4 vertebrae above that on the spinous processes of the lumbar vertebrae through C2. They arise from the transverse processes of the sixth to tenth thoracic vertebrae (T6 - T10). Located just superficially to the spine itself, the multifidus muscle spans three joint segments and works to stabilize these joints at each level. Erector spinae origin insertion and action .

The final group is the intermediate muscles, which help with the movement of the thoracic cage. A current literature review is warranted, however, given the complexity of LM morphology and the inconsistency of anatomical descriptions in the literature. The deepest fibers of the multifidus muscle in the lumbar spine (the laminar fibers) arise from the . Recall that the term origin refers. These muscles are small, but run the entire length of your spine. In addition to extending the lumbar spine the muscle also acts as a stabilizer. Begin by lying on your back with the hips flexed and the feet lined up with the shoulders. The multifidus runs parallel to the spine. Multifidus. Morphology of the lumbar multifidus (Bogduk 1997, Jemmett et al 2004, Kay 2000, Macintosh et al 1986, Twomey & Taylor 1994)The lumbar multifidus muscle is the largest and most medial of the lumbar back muscles. The Cervical Multifidus originates from the Superior Articular Processes of the Vertebrae. These muscles also contribute to side bending (tilting) and rotation (aka twisting.) They originate on the posterior sacrum, posterior superior iliac spine, and transverse processes of all vertebrae from the lumbar to C3. The multifidus is located underneath the semispinalis muscle. Multifidus: The muscle is situated underneath the semispinalis muscle. The semispinalis thoracis (Latin: musculus semispinalis thoracis) is a deep muscle of the back that overlies the thoracic part of the multifidus. The dysfunction can be caused by inhibition of pain by the spine. Multifidus insertion Spinous processes of vertebrae 2-3 segments superior to origin Multifidus bilateral action extend vertebral column multifidus unilateral action laterally flex vertebral column multifidus innervation dorsal rami ; The second group is the superficial muscles, which help with shoulder and neck movements.
