Multifidi and Rotatores
Multifidi and rotatores form a thick band of muscle that fills the lamina groove. They connect the transverse process of a vertebra to the vertebrae above it. The shortest strand is the deepest. As the strands lengthen to span more vertebrae, they become more superficial.
Rotatores:
Rotatores are the deepest muscle in the lamina groove. Rotatores connect the transverse process of a vertebra to the spinous processes of the two vertebrae just above it.
Multifidi:
Multifidi lay just on top of the rotatores. Multifidi connect from the transverse process of a vertebra to the spinous processes of the vertebrae 3-5 segments higher trapping two vertebrae between the attachments.
Multifidi attachments vary slightly in different sections or the spine.
Lumbar:
Origin – mamillary process
Insertion – spinous process of the vertebrae 3-5 segments above the origin
Thoracic:
Origin – transverse process
Insertion – the spinous process of the vertebrae 3-5 vertebrae above the origin
Cervical:
Origin – articular process (of the lower four vertebrae)
Insertion – transverse process of the vertebrae 2-4 segments above, up to the axis
