Cervical Rotator (Musculus rotator cervicis)
Educational content only — not medical advice.
Anatomy
The deepest, shortest component of the transversospinalis system in the cervical spine, consisting of brevis and longus slips that link adjacent cervical transverse and spinous processes. Arising from the articular processes of the cervical vertebrae, it ascends medially to insert onto the base of the spinous process of the vertebra above or two above. It plays a minor role in contralateral cervical rotation and serves primarily as an intervertebral position sensor.
Origin & insertion
From the articular processes of cervical vertebrae (C3–C7), into the base of the spinous processes of the superior adjacent vertebrae.
Action
Rotates the cervical vertebral column to the opposite side; provides essential proprioceptive feedback for neck posture.
Innervation
Posterior rami of cervical spinal nerves (C3–C8).
Clinical notes
Micro-trauma to the rotatores cervicis following sudden rotation or deceleration leads to profound involuntary segmental muscle splinting and painful torticollis.
