Innervation: accessory nerve (cranial nerve xi) and direct branches from the cervical plexus (c1-c2) Unilateral: flexes and rotates the head to the same side. Innervation: lateral branches of dorsal rami of spinal nerves c1 c6. Occipital bone (superior nuchal line and external occipital protuberance) The spinous processes of all cervical vertebrae via the nuchal ligament. Tilts to the same side (with shoulder girdle fixed) Rotates head to the opposite side (with shoulder girdle fixed) Innervation: cranial nerve xi (accessory nerve( and cervical plexus (c2 c4) Clavicular (anterior) part: lateral third of the clavicle. Clavicular (anterior) head: flexion and medial rotation of the gh joint. Spinal (posterior) head: extension and lateral rotation of the gh joint.
