The interspinous muscles ( Latin for "inter- spinal process muscles ", singular interspinous muscles ) or inter- spinal muscles are short skeletal muscles of the spine that connect the spinous processes of adjacent vertebrae on both sides of the interspinous ligament . Together with the spinal muscle , they belong within the "local back muscles" to the interspinous system ( Systema interspinale ) or the medial tract of the erector spinae muscle .

Depending on the location, a distinction is made between three sections:

The five interspinous lumborum muscles are located in the area of the lumbar spine .
The thoracic interspinous muscles are usually only weakly developed in some places due to the tile-like overlap of the spinous processes. They are located in the thoracic spine between the first two thoracic vertebrae , sometimes also between the second and third and eleventh and twelfth.
The six interspinous cervical muscles are located in the area of the cervical spine from the second to the seventh cervical vertebra .

The innervation is provided by the dorsal rami of the spinal nerves C1-Th3 and Th11-L5.

In ungulates the interspinales muscles are interspersed strong stringy and form planar belts , which as ligaments interspinalia be referred to. In the carnivores , however, they are muscular and extend from the posterior cervical to the anterior lumbar vertebrae.
