Rotatores cervicis consist of irregular and variable muscle bundles between C2/C3 and C7/T1.

Proximal Attachment
Rotatores cervicis arise from the supero-posterior aspect of the transverse processes of the cervical vertebrae.

Distal Attachment
They pass to the inferior border and lateral surface of the laminae of the cervical vertebra above.  

Nerve Supply
They are supplied by dorsal rami of C3 to C8.

Action
They are responsible for rotation between adjacent cervical vertebrae.
