📖 Static demo — read-only snapshot
You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:
- Global search (sidebar) is disabled — it queries the API.
- The JSON API and the API “Try it” playgroundaren’t included.
- The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.
Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.
Rotatores (Thoracis)
Deepest transversospinal muscles. Span 1-2 segments. Primary role is proprioception and segmental stabilization. No discrete cleavage planes between multifidus and rotatores.
Draft95%
Anatomy
- Origin
- Transverse processes of thoracic vertebrae
- Insertion
- Lamina and base of spinous process of vertebra 1-2 segments superior
- Action
- Contralateral rotation, segmental stabilization, proprioception
- Innervation
- Medial branches of posterior rami of thoracic spinal nerves
- Blood Supply
- Posterior intercostal arteries
