Transversospinales
muscles of the spine
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 spinae muscles.
Location
The three semispinalis muscles, span 4-6 vertebral segments:
semispinalis thoracis
semispinalis cervicis
semispinalis capitis
The multifidus muscle, and spans 2-4 vertebral segments
The rotatores muscles, lie beneath the multifidus, and spans 1-2 vertebral segments
rotatores cervicis
rotatores thoracis
rotatores lumborum

Begin with the source’s own compact description: “Transversospinales” is muscles of the spine. The dossier treats that line as a proposition to test through Transversospinales, muscles and spine, not as a finished interpretation.
Why this record matters
The phrase “muscles of the spine” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 19, 2026. The linked authority identifier is Q2606107. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
