Interspinales muscles. The interspinales are short muscle fascicles, found in pairs between the spinous processes of the contiguous vertebrae, one on either side of the interspinal ligament. In the cervical region, the cervical interspinales are most distinct, and consist of six pairs, the first being situated between the axis and third ...
The muscles connecting the anterior tubercles are termed the anterior intertransversarii. Those between the posterior tubercles are termed the posterior intertransversarii. Both sets are supplied by the anterior rami of the spinal nerves. There are seven pairs of these muscles, the first pair being between the atlas and axis, and the last pair ...
Deep muscles of the back. The transversospinales are a group of muscles of the human back. Their combined action is rotation and extension of the vertebral column. These muscles are small and have a poor mechanical advantage for contributing to motion. They include: the three semispinalis muscles, the multifidus muscle, and the rotatores muscles.
The erector spinae is not just one muscle, but a group of muscles and tendons which run more or less the length of the spine on the left and the right, from the sacrum, or sacral region, and hips to the base of the skull. They are also known as the sacrospinalis group of muscles. These muscles lie on either side of the spinous processes of the ...
Anatomical terms of muscle. [edit on Wikidata] The levatores costarum (/ ˌlɛvəˈtɔːriːz kəˈstɛərəm /), twelve in number on either side, are small tendinous and fleshy bundles, which arise from the ends of the transverse processes of the seventh cervical and upper eleven thoracic vertebrae. They pass obliquely downward and laterally ...
The multifidus (multifidus spinae; pl.: multifidi) muscle consists of a number of fleshy and tendinous fasciculi, which fill up the groove on either side of the spinous processes of the vertebrae, from the sacrum to the axis. While very thin, the multifidus muscle plays an important role in stabilizing the joints within the spine.

FMA. 71392. Anatomical terminology. [edit on Wikidata] The interspinous ligaments (interspinal ligaments) are thin, membranous ligaments that connect adjoining spinous processes of the vertebra in the spine. [1][2] They take the form of relatively weak sheets of fibrous tissue and are well developed only in the lumbar region. [3]
